Hi Dwight,
Thanks for the post. Very interesting indeed. I bought this online with only having a few pics to go by, and the dealer selling it new very little about Lugers. I wasn't really sure what I was getting, so I was either overpaying for a shooter, or could be getting something really neat.
As matter of fact, the takedown lever does have the bottom numbered, as does the side plate (see attached pic). The breechlock has been stamped "25" but at the end where the firing pin is inserted, it is stamped "64."
I will also attach pics of the toggle pin, and the bottom of the barrel (stamped "25" and "882" under). The (Hza) stamp very well could be a "j" but honestly, the more I look at it.. It looks like an "L" to me? Its worn just enough that I can't really make it out.
Thanks again for the help! This is why I have the Luger bug so much! Learn something new with each gun! Any more pic request, I'll be happy to post them.
Reggie
