Here are pix of the mag numbers next the s/n of the piece, plus a few others. I know the owner had it from the 1950s and may or not have personally brought it back from WW2. It was one of about 6 or 8 guns left to his friend when he passed ca. 1990. He wasn't much of a collector in that most of them were common hunting guns. I know this from my appraisal of the estate of the late owner in 2009, plus knowing both men from 1940. The holster is marked DLU 1941, P.08 plus Nazi eagle.
