Need help on DWM 1918

[Don M]

This grip strap is a veritable cornucopia of markings!

The crossed-out mark under the second lineout from the left appears to be SP.Bn. which represents the Schupo of the Saxon city or governmental district of Bautzen. The weapon number 694 would be consistent with this. I have a Luger marked SP.Bn.669. If correct, this was a weapon of the police of Saxony during the Weimar era. I, too, am curious about the x'd and lined-out marking to the left of this. Might it have been another "SP"?

If there is no evidence that it ever had a sear safety, it would indicate that it was probably removed from police service before 1933. However, no information was presented about the serial numbers on the frame and the barrel. Do they confirm that the upper and lower parts of this pistol are originally from the same gun? I have seen a few instances where they were not and it completely mislead the identification of the gun.
