Recently purchased a GRD F3 car without chassis plate, and am trying to determine history of car. The first US owner claims that the car was bought from Tom Wheatcroft through Mike Guy, and that the car was driven by Alex Dias Ribeiro in the '75 Monaco F3 race. It is a front-radiator config, so it would be either a '74 or an updated '72 or '73. If anyone out there is GRD knowledgable, please reply. Thanks.

I am far from being an expert of GRD's but from the 1975 Monaco Results I can see that Renzo Zorzi won the 1975 race in a #113 GRD 374 - Lancia/Repetto entered by Scuderia Mirabella Mille Miglia, Jac Nelleman brought his Texaco Racing Denmark/GRD Ltd #65 GRD 375 - Ford Pinto/Holbay in 10th.

Derek Cook, #80 374 & Henrik Spellerberg, #66 374 both failed to qualify while the list of DNPQ's goes

Thorkild Thyrring, #67 374
Silvio Artina, #96 374
Gianni Giudici, #101 374 Lancia/Repetto
Duilio Ghislotti, # 102 374
Luigi Pozzo, #106 375
Anders Olofsson, # 118 373
Giancarlo Comazzi, #123 373

DNA's are listed as :-

Werner Fisher, #42 373
Paul Mativide, #62 375
Marcos Moraes, # 63 374
Dan Greer, USA, Challengers Racing Team, # 69, GRD 373
John Rust, GB, Challengers Racing Team, # 71, GRD 373
Doug Bassett, G, F.P.A. Pichmastic Ltd # 76, GRD 374
Ian Taylor, GB, GRD Ltd, # 90 GRD 375

All Ford powered unless otherwise stated.

Alex Rideiro DNF'd from the lead after an accident with Tony Brise in a works March 753 Toyota/Novamotor

I thought I ought to check the 1974 Monaco F3 results and we have a surprise in 6th place :-

#57 Alex Ribeiro, BR, Hollywood International Racing Team GRD 374 - Ford Lotus TC/Novamotor

Which is still along way from saying he used the same chassis you have but it could be an important clue if you come across the remains of a Hollywood paint scheme :-)

I notice that Tom Wheatcroft ran Roger Williamson in a side radiator GRD in 1972

I hope that 10 and a half year wait was worth the it, and that you are still enjoying your GRD what ever it's history :-)

Ribeiro's Monaco car in 1974 was almost certainly his regular car used in the 1974 British series [GRD 374 056-F3] Chassis number observed on Ribeiro's car at Oulton Park 12.4.74.
Quite why, or how, this car would have gone from Tom Wheatcroft to Mike Gue [presume that's who is meant by Mike Guy] to Ribeiro is a bit beyond me, since it was a semi-works car new in March 1974.
The numbering of this car, however, suggests it started life as a 373 or B73 since there are 1973 production cars numbered as high as 078. GRD seem to have a policy of doing this with upgrades keeping the original chassis number but changing model number [Jo Marquart also did it at Modus and Argo]

There's no race observation of a 373-056, which is not the same as saying it didn't race. I doubt that Wheatcroft would have owned it though, since he'd already bought two GRD F2s for Williamson [051 and 052-F2] and the team had finished with F3 at the end of 1972. In 1975 056 was sold to Brian Henton who used it as a rental car, running Derek Cook in it at Monaco. I suspect that Gue got involved in selling it after that.

The plot thickens Derek failed to qualify at Monaco in 1975 who is Mike Gue ?

He?

In the 70's Mike Gue was based at Soho Garage Calne Wiltshire,
dealing in secondhand race cars ect.
Nelson Engine Services operated from the same premises.
