Hi again Bill! So far so good. We already know the "S/42" production was about 38,000 give or take a few. The production of the "42" code was about 86,000. So your Luger is a bit more valuable. Also we know the serial number didn't begin until the N-Block, so by elimination your pistol is a Q-Block which was near the end of the "S/42" production and the beginning of the "42" production. Sounds like you are making some good progress.
