I've recently aquired a Unique Model 17, SN. 24733, from the son of the vet who brought it back. It's WaA251 marked, but the mark is hard to read, as it is stamped over rough milling marks. The whole pistol is very poorly finished and shows many unpolished milling marks all over. The silde is stamped 7,65 COURT 9 COUPS "UNIQUE", and the black plastic grips are marked 7.65m/m 9 SCHUSS. I believe it is a early piece made up from unfinished parts after the Nazis took over? Comments welcome. Sorry, no pictures available.
