Thanks for the info. I did do a Google search for that phrase and didn't find much except the town. I figured it ment State Police for that town. I did find this:
In the town of Mesto Libavá there were 345 houses in 1929 and 2,237 inhabitants lived there. Of these, 2,181 were considered Germans and 21 Czechs.
After the Second World War, the German-speaking population was resettled in Germany. Immediately afterwards, the entire area around the city was used for military purposes as a military training area.
So I'm guessing it was used by the local police in WW2. That might explain why the Bakelite grips were swapped out for wooden ones.. Anyway, thanks again.
