Here is my new "toy", just got it this week and have not had a chance to try it out yet.
Best I can tell from reading it dates to about 1934.
No box, but two 5rnd. magazines!
One magazine is numbered to the toggle assembly; the other to the barrel number- so I have part of two original kits.
Anyone have an empty box? Or a spare barrel nut, as it should have two?
Also shown installed in my shooter 1937 upper on my basket case
1906 lower, which is functional using "borrowed' parts from another of my Lugers.
Still need an upper for it, but did buy a 6' Navy barrel today!
