To be fair, Greenamyer's 104 was a one-off, not so much stripped down as scratch built from borrowed basket cases leaving out all the military bits, rather akin to mending a clock and ending up with a saucer full of sprockets and springs. Legend has it that nobody could be persuaded to lend him an engine at first in case it tempted him to fly the thing!
Incidentally Mr G was also responsible, nearly 40 years on, for taking Fritz Wendel's 1938 piston record past 500 mph; it was this achievement which decided him to have a crack at 1,000.
