T. Lynch gives us some answers:
"In 1956, John Edgar was waiting for
delivery of his 410S Ferrari, which Shelby was to drive. Chinetti
had sold the car to Edgar, and to accommodate him while he waited, Chinetti
leased a couple of cars to Edgar for Shel to drive. One was the 500
TR that Shelby used to win Brynfan Tyddyn (McAfee was second in Edgar's
550 Porsche). Another was the Ferrari
375 GP car pictured on your site.
Shelby drove this car to victory in three
hill climbs in 1956. First was Mt. Washington, held on 15 July.
The following Friday, Shel won at Giant's Despair. The next day he
won Brynfan Tyddyn in the 500 TR. Then on 5 August he used the 375
GP to win the Breakneck Hillclimb. The GP car, as you mention,
is one of the four that attempted to qualify for Indy in 1952. It
is the Ascari car, the only one that qualified. Note that the body
had been modified since the car ran at Indy. The car's original serial
number was simply No 1. That was changed to 0388, in Ferrari's normal
sports car numbering series, probably when the bodywork was modified."
Photographer Earl Gandel offered an interesting
"One other fact about the Ferrari; a
technical fix made to keep the rears on the ground during acceleration
at the hill climb was a lead weight, wired into the tail of the car after
a ragged hole was cut in the metal. Ah, '50's technology."
