unit Mark 1920

[sej-gun]

Hi Don.
Thanks for the answer.
Is it correct that the Luger was started into the army, and then came into the Polizei in 1922, and got a new number in 1932, after that the Luger must have entered the army again, and come up to Denmark (1940-45). It got Police rework proof marks, on the Receiver, right side. Left side and front of frame: #1699 n, and under the n is there a small letter, maybe an e ??. (The same on the barrel)
Thanks from
Jes.
