Hi , i have a little question about the engine n° on my 1930 S6 on top of crankcase alongside magneto.Normaly the engine n° on a 1930 S6 must begin with the EQ predix followed by 4 numbers , but on my engine i c'ant find any prefix , there's only 4 numbered code on crankcase on the left of the front cilinder,but on the top of the crankcase alongside magneto there's a big capital X and above it the code V2 D (D with the K in it ).
Can anyone tell me a bit more why this is not as it should be.
Regards
Aphex
