Alright guys. Check it out. Full rig. L.P.288 on front strap and back of holster. 288 also appears on the bottom of both magazines and take down tool. One mag is marked 1 and the other is marked 2. Waffenamt on right side is WaA66. No manufacture mark on toggle and no markings on chamber. N proof on left side of frame and under the barrel. SN is 6740 with a small "t" under sn on frame and barrel. Every part that has 40 stamped on it. SN is on the back of the grip plates too. Back of holster has Schambach & Co Berlin 1929, with a small sunburst under the year.

Here is what I have uncovered so far. Having a T in the sn with no manufacturer makes it a "sneak" from the late 20's or early 30's. L.P. is a Prussian Police mark for the air survaillence unit at Pommern. So I'm thinking this is the 288th full set up issued in 1929 or 1930. Your thoughts and comments will be greatly appreciated.
