I have one is serial no. 43923. It is marked WaA 140. It also has all of the Belgian commercial proofs, and some of the Belgian military acceptance markings.
(At that point in time, the Beligan militay marking were "C" in square and small crown "AC" and small crown "GC". My Hi-Power is missing the the small crown "GC".)
The Germans did not mark all of the Belgian Hi-Powers that they acquired. Apparently yours and mine went back into the factory for some reason (ie: repairs) and then was marked before it was re-issued.
