This adds confusion to my understanding of the origins of these pistols. First, I understand they were imported from Bulgaria. However, they might have traveled through Germany and to F Jagd on the way--nothing puzzling there. However, these were refinished in classic eastern bloc style with the "dip blue" and some black paint over the rust spots. The WaA251 stamp does not appear to be on top of the refinish but under it. Otherwise, there would be a disruption of the surrounding finish, wouldn't there? Do the WaA marks appear as though they were applied after the refinish?
