In my small collection, this one is the winner: G 41 (Walther system) made by Berlin Lubecker Maschinenfabrik at the beginning of 1944. This rifle has probably been "left back" by a German soldier somewhere in North Italy, so hasn't import markings or Italian fire proof markings. All matching, it has some light pitting here and there externally, but fortunately the stock wasn't touched at all.
BLM produced around 90.000 rifles, on a grand total of 120.000 G 41 (Walther system) ever made. This one hasn't the scope rail for the ZF 41, feature dropped around "e" block suffix.
