Hi all,
I just acquired a gearbox shell for my P11A build. It is serial # P11 19958. Does anyone know whether the P11 gearbox #'s can be correlated to a production year?

Thanks,
Ed

The gearbox serial numbers probably could be mapped to a year range, but I couldn't find a source. I only looked for 10 minutes though. The gearbox in my P11 is P11 / 18057 and the bike is 1967 range according to the Norvil database for engine serial numbers.

The P11 Mailing list has a data base. Your g/b no fits very well in the 1968 model year range. The g/b no on my 1968 P11A is 20010.
