Those are mostly made up number/letter combinations trying to look like an old dry lakes racer

 

Late 40s early 50s there was only A, B, C, D classes, Fuel and Gas classes came in later, first mention of gas is in B-ville program was '56.

Rules for 1950

 

Should mention Russetta classes were arse about, A for largest displacements and C for small displacements

 

Jeez... was there ever really a two page rule book? Gary
