Bugattis Did it Too

Continuing the Loose Fillings Blog about the
history of air-cooled racing cars …

IN 1948 THE COLOURFUL SPEEDWAY DRIVER Spike Rhiando had the idea of putting an 8/80 JAP V-twin engine in the back of his new Cooper. Little did he know what he was starting. With this brilliant combination of power and lightness, a number of drivers – and the novices Stirling Moss and Peter Collins – set out to do battle against the front-engined might of Ferrari, Maserati, Alfa Romeo and others.

A number of development strands coalesced in the making of the Coopers and one of them first emerged in California way back before World War 1. We can even precisely pick the day because it was at a car race at Venice, near Los Angeles on 10 January 1914. There was another 20th century first there too – the debut before the movie camera of Charlie Chaplin’s famous Tramp.

The wholly improvised film was largely about a bewildered little tramp getting in the way of the racing cars. As a logical step up from ‘pushmobile’ or ‘soapbox’ racing, the races were for cars which boys (no girls are mentioned) had built and fitted with motorcycle or boat engines.




Charlie Chaplin’s first appearance as The Tramp was at  race meeting in the streets of Venice, California in January 1914, Cars were boat and motorcycle-engined creations built by the boy drivers themselves.

Watching all this was 17 years old Harry Hartz who had been building a twin-cylinder motorcycle engined ‘roadster’. He quickly changed his plans and was soon the champion of this new class of racing for under 19s, which rapidly expanded through southern California. In his ‘twenties Hartz was to become one of the all- time Indianapolis ‘greats’, being placed in the top four no less than five times in the nineteen twenties and winning the American Automobile Championship in 1926.

Young Hartz wrote three articles in the magazine Motor Age in May 1917, which put the history and construction of what he called the ‘junior racing car’ on the record. While early races had been classified according to the number of cylinders, a new formula was soon adopted, said Hartz.

What he called ‘Class A’ had a front mounted engine ‘under the hood’. Drive was by chain or belt to a jackshaft and then by chain or belt to the rear wheels. Hartz’ first car, as used at Culver City, Los Angeles in 1914, had been one of these but he found that it wanted to tip over on turns. That was when he had the idea of the Class B outside engine location.


4.Kids.HarryCar.jpgHarry Hartz, standing, shows how his racer works. The Indian V-twin engine was slung out on the left-hand side, like the example below at Tacoma, Washington in September 1914.

4.Tacoma.39053 (2).jpg

‘Class B presents an entirely different view to the eye,’ said Hartz. The engine was placed on the left and outside the chassis, driving to a jackshaft or directly to the rear sprocket. Cars sometimes had three-speed gearboxes, but for racing, Hartz said, these were unnecessary.

With this type of car, Hartz said, he had won practically all the races run in the west; at Ascot recently he had run a mile in 54 seconds, which meant a speed of 80mph on the straights and 60mph on the turns.[2] He had a 75in wheelbase and 26 x 2¼in interchangeable wire wheels. Such a car would cost anything from $100 to $300. ‘Interest in the tiny cars is growing rapidly and it is believed that in the near future the sport will have grown so that it will rival motor car racing in the eye of the public,’ concluded Hartz.

After World War 1 these and other cars developed into what became known as ‘midget’ racing on short urban dirt tracks. In the mid-‘thirties, this spread like wildfire to the middle and eastern states of America, where it soon became one of the most popular spectator sports. Spot fires spread rapidly to Australia, South America and soon reached Britain, where there had already been tentative attempts at dirt-track racing.

Probably with an eye on the popularity of motorcycle speedway, on 23 June 1928 the Junior Car Club (JCC) had held what it described as ‘Britain’s first authorised dirt track car racing’ on a ½ mile trotting track at Greenford in Middlesex. The final was won by Archie Frazer-Nash. It didn’t lead to more than occasional events of the same kind, but motorcycle speedway promoters, always looking for novelties, sometimes had car races or record attempts during their meetings.

For example, Light Car and Cyclecar reported that on 1 November 1929, at Leicester’s Melton Road speedway before 10,000 spectators, H Brayshaw in an Alvis had won the mile scratch race. A Shipley had won the handicap in a Salmson. ‘There was a lot of excitement’, it said, when at Wembley Stadium on 1 October 1931 ‘HJ Aldington, Mrs Wisdom and RGJ Nash drove Frazer Nashes before a roaring multitude which seemed to number about half-a-million dirt track fans:

The idea was to set up a car lap record, upon which attempts will, no doubt, be made from time to time. At the end of the programme when the ordinary gladiators had done their stuff, the heartening whine of a supercharged car engine beat upon us in the packed stands, and out into the arena came Mrs. Wisdom and her venerable supercharged model which she and her husband have handled at Brooklands, Shelsley, in trials and everywhere else for some years.

There was a tremendous roar of welcome from thousands of throats as she put in a couple of preliminary laps and then as she shot across the line for her timed lap. Her broadsiding was spectacular and the crowd shouted its applause. The tail of the car swung in a great arc; once it thumped the fence, and a wave of dirt shot up from her rear wheels in the accepted manner. Her time was 24 seconds

The evening came to a close in a highly dramatic manner as Nash – who, having burst ‘The Terror’, had taken over Mrs Wisdom’s car – hurtled into one of the bends, with the bonnet of his car pointing at right angles to the line of travel, the dirt heaped up in front of his sliding wheels, the car tilted, hung poised for a breathless second, and then, while the crowd leapt to its feet, went right over against the fence. Happily no one was hurt, and crowds roared and cheered its relief. I have never seen such enthusiasm for a car event.

Eventually this activity came to the attention of the powers-that-be, the Competitions Committee of the Royal Automobile Club (RAC). It had given a bit of thought to the dirt track business back in 1928, when it had issued a permit to the Junior Car Club (JCC) for its racing at Greenford. It had also agreed to inspect a track at Audenshaw, near Manchester. Various other brief but inconclusive mentions can be found in the minutes.

On 19 September 1933 it was recorded that a request had been received for inspection of the track at Belle Vue speedway, Manchester, with a view to issuing permits. The committee agreed to carry out an inspection and then, on 11 December, without further explanation, it was minuted, ‘Speedway car racing on loose cinder tracks did not constitute car racing as visualised by the RAC General Competition Rules.’ The Competition Secretary noted, ‘not to control’ and that a sub-committee was to ‘deal with what is required’.

Only a few weeks later it is briefly recorded that the ‘Committee considered a reference back from the [main] Committee of the Club re speedway’. It seems the status quo was to remain in place, and the RAC was to purport to have control of speedway car racing. Certainly an RAC permit was issued for a short lived revival of racing at Greenford on 5 May 1934 when Viscount Curzon was head steward.

1936 Barnet-001.jpg

Dirt track racing at Barnet, north London, c1936. Left is Vic Gillow who was a well-known Riley driver at Brooklands. Right is Les White who later raced a Skirrow.

There was racing at Barnet on a track which had started out as grass in 1929 but eventually became a dirt track. On 28 July 1936, the North London Motor Club was held to account by the RAC for its activities at what it called ‘Barnet Speedway’. Again the minutes are brief, but the club had obviously (at last?) made an application for approval of the track, it had been inspected, a fence was required all the way round and if that were done it could be ‘classified as a permanent track for the purpose of General Competition Rule No.15’. In fact it closed down and the land was sold for housing.


Even Bugattis did it. This was an unsuccessful attempt at starting up American-style dirt-track racing at Greenford, Middlesex in 1934. Photo courtesy Ivan Dutton.

While it lasted even Bugattis did it here and there but details are few and far between. Ivan Dutton has a photo of one racing, probably at Greenford in 1934 when competitors include “A.Baron 3 Litre Bugatti’ and ‘TP Cholmondeley-Tapper 11/2 Bugatti’. In his book, Amateur Racing Driver, Tapper reported that he won the final but instead of his two guineas starting money and £80 prize money he only managed to take home £20 and an IOU which he still had at the time of writing.

I have a photo I have wanted to use since I copied it 40 years ago. It shows Cec Warren’s type 37 leading two more Bugattis at Richmond, Melbourne sometime in 1932. There were also, as Pur Sang reported back in 1980 (V20,#2, pp26-27), two Bugatti-engined American midgets, one of which, at least, had a Brescia engine. I believe Ivan Dutton has one of these engines along with an interesting collection of dirt track cars. These include two of the three or four surviving Skirrows (I have another) and one of the cars built for Belle Vue speedway which has an Elto two-stroke outboard motor.


Bugattis did it in Australia too; Cec Warren leads three of them at Richmond, Melbourne in 1932.

Meanwhile, organized car-only dirt track team racing on motorcycle speedway lines, independent of the RAC, made its British debut at Crystal Palace, London on Good Friday, 30 March 1934. There was a large crowd, said Light Car, giving it a smaller headline but equal space to its report of the Monaco Grand Prix on the same page.

There were three teams, each of three drivers and a reserve. Crystal Palace was captained by Jean Reville and drove Palmer Specials (front wheel drive BSAs), Wembley Park was captained by Victor Gillow and drove Rileys while ‘New South Wales champion’ Tommy Sulman captained Wimbledon Park driving a ‘Bitza Special’. Dick Nash in ‘The Spook’ made a record attempt over two laps. ‘Cutting-out on the bends and zooming with a roar along the straights’, he was said to be much faster than he looked, with an average speed of 40.81mph.

This team racing was initially concentrated on London and the Home counties. The cars still tended to be stripped-down sports cars but it was becoming clear that modified road cars didn’t provide the spectacle that made solo motorcycle speedway a big hit and car dirt-track sensational in America. The British motorcycle tracks, with a deep surface of cinders, short straights and tight turns were not suitable for the cars then being used.

What was needed was cars specifically tailored for the job and, as with the solo motorcycles, it took several years of trial and error for a suitable format to emerge. New rules were promulgated to define the midget racing car. Engine capacity was to be limited to 1100cc and superchargers banned. Wheelbase was to be no more than 56in and track was not to exceed 42in. Wheel diameters were to be between 12in and 14in and exhaust pipes were to extend to the back axle.

One of the earliest cars built to this formula was Jean Reville’s ‘Gnat’, and late in 1934 it was announced that it was to go into production with talk of a run of 50 cars. Most of these weren’t to eventuate, but at least four were made, and at least two had 500cc single-cylinder engines.

The twin-cylinder version of the Gnat was distinguished by having a fore-and-aft, big-twin engine with the rear exhaust exiting between the driver’s legs. It was every bit a midget, and was billed as ‘the world’s smallest racing car’, a clever claim which appeared in newspapers all over the world.


Four of Jean Reville’s Gnats put on a show for the press at one of the London tracks in 1935.        

In late 1935 Jean Reville took a small team of drivers and three of his cars to race in Australia where he settled down, never returning to Britain. But others in Britain had realized the potential of the big-twin JAP, and better midgets were to follow his pioneering efforts. The 1935 season had seen midget car racing expand to more motorcycle speedway venues around Britain, not without a great deal of opposition from two-wheeled interests.

The following year the Eric Fernihough inspired JAP 8/80 engine was put into production for the dirt track Skirrow Special, Spike Rhiando raced one and, after the war, he put the engine in his Cooper. The rest, as they say, is history.


Bill Reynolds took this JAP-engined Skirrow to New Zealand then Australia in late 1938. He raced a Cooper 500 post-war, amongst other cars.

John Staveley in The Bulletin of the Vintage Sports Car Club

On first opening this heavy, well produced book it immediately becomes apparent that it is … a vibrant story of motor racing starting before the turn of the twentieth century but quickly moving on to post World War 2 airfield circuits.

… an important work, written in an entertaining style, beautifully illustrated and great value. What a good book! Highly recommended.

Doug Nye, author of Cooper Cars on the Nostalgia Forum

… here’s a beautifully-designed, very well-produced, highly detailed and sophisticated piece of engineering and sporting history—really well worth the money. Respect!

He has spread his remit to cover the entire background story of small capacity competition cars after much diligent research, and deals with the nativity of the 500cc movement itself in really interesting depth. I rate it as an important, hefty, and good looking addition to any real motor sport enthusiast’s book shelf.

John Medley, author of Bathurst – Cradle of Australian Motor Racing
in The Oily Rag

This is a marvellous book. You should buy it. It is filled with fascinating detail, a clear story line, broad and deep in its history and humanity, astonishing in its memorabilia and automobiliana, the author’s research and footnoting a model for other writers, the author’s hands-on experience in the field impeccably unmatched … The book is well produced, thoughtfully designed, and too heavy to read in bed.

David Moore, Shelsley Walsh archivist in MAC News

This excellent book is so much more than the title suggests as it covers a wide motor racing history …  the JAP and Vincent units are fully illustrated by the author who clearly knows his subject in great depth … Interestingly, the author not only describes the origins of the cars themselves but also paints vivid pictures of the motor racing, social and political scenes of their eras.

Jerry Sturman in Speedscene, journal of the Hillclimb and Sprint Association

Fills a significant gap in motorsport history … All enthusiasts will want to have this one on their shelves … Entertainingly written and superbly laid out … the book is a visual treat as well as being a meticulously researched, in-depth survey of the history and development of the motorcycle V-twin engine in competition.

Mike Cooper, Managing Director, Cooper Car Company Ltd
I have been buried in the book all weekend. It is a fascinating read and I am sure many other motor racing enthusiasts will really enjoy it.



Ian Garmey reports that the Waitemata branch VCC annual Chelsea hillclimb was held in the stunningly beautiful park surrounding the CSR’s Chelsea sugar refinery with no less than five air-cooled cars competing, four of which we have photos here.

19/20 September

Some great pics by Bob Ross. Here we have three twins racing, not a sight you would see often anywhere nowadays. The blue car is Garry Simkin’s Mk4 Cooper Vincent, the red car number 26 with black helmet is Brian Simpson Mk9 with #2 Derry Greeneklee, Mk6 Cooper JAP behind him. Keeping the 500 flag flying is #27,  Andrew Halliday Mk5 Cooper Norton.







Here are some photos I downloaded years ago from an obscure website which had a number of albums of early ‘fifties Ulster motorsport including Dundrod 12 August 1950, when there was 74 miles handicap race over 10 laps. As well as Ron Flockhart who is pictured in the book, there were 500cc entries from Joe Potts jnr, Comish Hunter and Pat Prosser. Prosser was in a Cooper and crashed, I don’t think Potts started and Hunter, #31, was, like Flockhart ‘unhappy’ according to Autocar. These poor resolution but useful photos show the front and left side of the Flockhart car #22 (note the forward steering rack position) and Hunter’s #32. If nothing else these add a little to what is known of the early Potts cars. Also posted is the entry list from the programme courtesy Richard page.

Dundrod entry

Power Without Glory: Racing the Big-Twin Cooper by Terry Wright was published on 2 November 2015. Here the author is starting to publish some of the mass of material  he has collected that didn’t find its way into the book.


Following Kerry Horan’s comments (thank you, see  ‘Comments’ PREVIOUS POST/JOE POTTS MYSTERIES below) here are a couple of complementary lists of engines; they seem to be different ‘views’ of the same factory records. The spreadsheet came from Brian Greenfield. The John Marshall article is obviously from the VOC mag.

The two engines for P Monkhouse are a mystery. Peter Monkhouse was killed racing in Italy April 1950 spo assuming it is the same person the date on his two engines of 1.10.50 is strange

My best information on ex-factory Vincent-engined cars is as follows:

1948/9 prototype car reportedly for George Abecassis but raced by John Cooper at Goodwood September 1949 then this, or another car delivered to George in 1949 and first used at Goodwood.

1949 cars for  George Hartwell, Pat Fergusson and Eric Winterbottom

1950 car for John Green maybe using engine ex Pat Fergusson

1950 car supplied without engine for John Snow who fitted an engine in Sydney from a complete Lightning that he had bought.

It would be interesting to find out if anything is known about the Monkhouse engines #1485 and 1486. Maybe someone in the VOC can inquire of the Registrar.



Just as I was doing the final proofing on PWG I had some useful information from Vernon Williamson who owns the first of Joe Potts ‘JP’ cars. I had captioned a picture of one of the first two JPs at Dundrod in August 1950 as being driven by Mirrlees Chassels because that’s what it says in the programme and the race reports. But according to Vernon, Dr Chassels eyesight wasn’t too good that day (seems there was some sort of problem with the track doctor – a hangover perhaps?) and Ron Flockhart took over the drive;  Be that as it may, the caption was changed as more information emerged from Vernon about the JPs.

Joe Potts had hillclimbed a Cooper at Bo’ness and Rest and Be Thankful in 1949 and reportedly raced at The Curragh in Ireland. It is known from factory records that early in 1950 Vincents supplied him a Black Lightning twin engine (998cc)and a Grey Flash single engine (499cc). Later he had one of the rare speedway engines but I am not sure what car that was for.

His first race appearance with a Vincent was at Silverstone for the British Grand Prix meeting on 13 May 1950 with the dark, probably green Cooper as pictured below in the paddock. He was eighth in his heat and his finish in the final isn’t recorded .


Several points can be noted about this car and readers might like to add their own observations.

It has the small brake drums which are believed to be the original aluminium wheels used before the magnesium type became available, maybe as an optional extra, sometime in late 1948. The wire-spoked steering wheel is characteristic of the earlier cars too. On the other hand the twin filler cap header tank which normally accompanied the recirculating oil systems of the Vincent and JAP big twins tends to suggest, maybe, a later car. Of course the later, or a modified tank could simply have been fitted to an earlier car when it had a recirculating oil engine installed. Or maybe it was supplied as a 500 (which is what Potts used in 1949) with the equipment and dimensions to suit a big-twin?

Note how low the two-exhaust pipe holes are. These can only be to accommodate a ‘low-slung’ Vincent with the semi-integral gearbox cut off so that the engine would sit lower without the Vincent clutch fouling the chassis rail. Usually an Albion gearbox was used and it is thought that is what Potts did. There is no record of him competing with the twin before this Silverstone photo, but it is probable that he had tried the engine in the car (wouldn’t you?); thus the twin exhaust holes that can be seen. Here is a Cooper Vincent with the engine in the normal ‘high’ position –  it’s John Green with a new car at Goodwood on 27 May 1950.

John Green Goodwood 27 May 1950 001

Potts’ next outing, and his first with a twin, was at the Manx Cup race at Douglas Isle of Man on Thursday 15 June when a  host of Cooper twins competed and all broke down. Strangely Pott’s was entered with a JAP twin and there is no direct evidence what he ran but it would seem probable he would have used his Vincent twin.

There is a photograph of the other side of his car at Douglas in PWGl which shows he didn’t have the bulge in the engine cover for the front carburettor which Vincents normally required. That suggests he was running a JAP but on the other hand, if the engine was lowered he wouldn’t have had a problem with carburettor clearance. Starting from the back row, Potts only lasted for two laps of the 18 lap race over 69.81 miles.

He competed at Bo’ness hillclimb on 24 June apparently with the 499 Vincent when he was a poor second to Comish Hunter. He was  at Rest and be Thankful a week later again running second, but closer, to Comish Hunter’s Cooper JAP. There is film at*&search_join_type=AND&search_fuzzy=yes in the National Library of Scotland that shows him, if only briefly, in a bronze or gold coloured car and that seems to be the last we see of Joe Potts in a Cooper. Potts was the first car to start.

Within a few weeks the first two JPs were in action at Dundrod on 12 August 1950 with Ron Flockhart in a Vincent twin-engined  twin-tubular chassis and a distinctive steering rack position forward of the Cooper-type front suspension. The body could be Cooper or is more likely a replica with a slightly longer nose, maybe to accommodate the forward mounted steering rack. There is a photograph of this car in PWG, as is mentioned above, and when I find it I will add a picture of the other car at Dundrod where neither did very well.
