Yes. Oscar hired a friend of mine to put postcards with the Tamiya Honda F1 car under the wipers of "high end" cars in the paddock at the USGP at Watkins Glen. I got to know Oscar years later after having crewed on that very McLaren when Warren Agor bought it to race in the Can-Am series.
Good Dearborn Assembly video here: https://www.bing.com/ck/a?!&&p=3d94227f4a6f997d7d4750711eb770981daf4fd08d16d29f63044f420b77ad7cJmltdHM9MTc0NDc2MTYwMA&ptn=3&ver=2&hsh=4&fclid=1c385dad-368d-6a4a-1e47-4f6d37ef6bc6&psq=nowhere+to+hide+video+martha+and+the+vandellas&u=a1aHR0cHM6Ly93d3cueW91dHViZS5jb20vd2F0Y2g_dj1GTkZES204RjRoZw&ntb=1
Rex, I produced and ran the GT reunion! We were in the trailer at the entrance to the GT display area. There are more pictures of the cars here: Pictures/videos from the 2024 Gt Reunion | GT40s
And merch from the reunion is still available: Ford GT Reunion Merchandise - Ford GT Reunion 2024
I knew Oscar, a real piece of work and one of the nicest guys you would ever meet. He was the real thing, friendly, honest and enthusiastic! Last saw him at the Glen vintage a few years ago vintage pushing his kiddie formula race cars. In the late sixties he paid me and a friend to put postcards with the Tamiya F1 cars on windshields. I still have some somewhere.
FYI on a Salisbury differential as used by all Cobras, the gear case ("pig, chunk, carrier, etc.") was red oxide as just as on a Ford 9", the carrier was dipped before machining.
Would love the original. IMC had great box art. I do have the GT playing cards that have that art on them you got by sending 25 cents and a coupon from the kit box.
And I know Allen Grant, who owns a MK 6. Always loved that car. Took my 1/32 Monogram slot car and using a Car Model or Model Car Science magazine article, modified it have the flared fenders of the reworked Mecom car. I ruined a great car!
