Trying to identify, and date, this pistol I picked up. Break action, single shot.
only markings are:
Top of barrel:
O. Geyger & Co. Berlin

Side of barrel:
0,15 grN.G.P. M/71
2,14 gr Bl.

Bottom of barrel:
B (with crown) G (with crown)
U (with crown)
611

 

[Alpo]

0.15 grams (2.31 grains) of Mauser 71 smokeless (N - Nitro - smokeless) powder
2.14 gram (33 grains) lead bullet (Bl G" for Blei Geschoss [plain lead] bullet)

B - proofed using Mauser powder
U - definitive proof
G - rifled barrel

These proofs are from 1891 to 1939. They quit listing the powder charge after 1912.

Quite possibly the 611 is the date it was proofed - June 1911.

Sounds like a 22 short. Possibly 22 Long, with that 33 grain bullet. Certainly not a Long Rifle, so even if one fits, don't shoot one in it.

Rimfire?

Pretty cool what's it worth?

It is rimfire. As to what it's worth, I'm guessing probably half what I paid
