Jes,
Since Ron has some difficulties with spelling
, I'll add my two cents:
These marks are from the Schutzpolizei (Large city uniformed police) of the K�¶nigsberg district of the Prussian Province of East Prussia. There are actually two marks. The first is S.Kg.4.63 and represents weapon no. 63 of the 4th Hundertschaft (Company) within this district. This mark is in accordance with marking orders issued in 1922. The second mark is S.Kg.1141. This is in accordance with orders issued in 1932 that eliminated the designation of the Hundertschaft.
I am building a database of these marks and would appreciate knowing the serial number of this pistol, including letter suffix, if any. Thanks very much.
