You may want to check with the folks at the German Gun Collectors Ass'n website. I passed up on a chance to buy one a few years ago and still regret it. Subject to the rule about buying the gun and not the maker, BSWs were well made and reflect the quality of German making at the time.

Posting some pics (including the proof marks) will help elicit some more specific comments.

Such a long, long time to be gone, and a short time to be there.
