Model 1900 Luger

[jasafn]

Gentlemen,

Thank you all for your help. I will take some pictures a.s.a.p. but I can tell this pistol never had any special rear sight. I am not sure about the original barrel but the one it came with was done from m/20 barrel no doubt. Grip safety was cut off and modified for safety catch new way. Leaf main spring was replaced with later P08s main spring with some tiny modification. All these reworks are removed now but nothing original was not ruin. I got the pistol about year ago and I have been doing research ever since. Parts have no serial numbers except upper receiver has #06 underneath. All main parts have same number "2".
The tiny leaf spring of grip safety was removed during the rework and when I bought a 1900 model spare part from States I got 1/3 too wide part.

There is no GL on rear of toggle. That I checked first when I bought this piece.
