Ballester Molina With B Prefix

[M62man]

I am hoping someone may be able to shed some light on this. I have read on several forums that B Prefix Ballester Molina's are serial numbered up to 21000. However, I may be buying one with a B prefix that is numbered at 22xxx. Could this be possible? If so where does this one fall into the light of being used by the SOE? Thanks in advance.

This is about as much info as I have seen regarding British issue BM pistols

Thank you. I’ve seen that thread before and it’s really great information. My question was do all the British contract guns end at serial number 21000? I’ve see some above that number. Can anyone corroborate this?
