From 1942 to 1950 it was just numbers I think. 410th bike in 1950 ?

Bikes this old are not my strong point, I'm a child of the 1970's lol

These were a mass-produced product, so I'd expect the numbering to be sequentially ascending, not using any digits as date identifiers. They'd be producing thousands of frames a year not hundreds. Low private car ownership back then, bikes were mass utility transport.
