My Plunger Frame number is ZA7.S.16245. I have a B.S.A Owners Club dating certificate from 2009 stating this bike was shipped to Sydney on 10th November 1950. Therefore, it should be a 1951. But, as I read the engine / frame numbers list I see it as showing mine as a 1952. 1951 up to ZA.7.S 14001 then 1952 ZA.7.S 14002 to ZA.7.S 26001. Making it a 1952 Frame.
I have re-read this list a couple of times but can't see the wood for the trees. Am I reading this incorrectly?.
Whilst we are here my Engine number is ZA10. 8318. 1952! is that correct?
