Finding a matching mag is an almost impossible task. It does happen but not often. Don Hallock has a list of mags. Can't seem to find his email. By the way your 1937 luger is not a BYF. The s42 code was replaced by a code 42 and then by BYF in 1941. Good luck in your search. Welcome to the forum. Bill Try
