GREAT REVIEWS OF POWER WITHOUT GLORY

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.

 

CHELSEA HILLCLIMB

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.

MORE EARLY POTTS

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.


MORE ON VINCENT ENGINES IN COOPERS

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.

JOE POTTS MYSTERIES

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 http://ssa.nls.uk/film/2120?search_term=speed&search_fields=Film.*&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.
