The rifle still has the Austrian Vienna proof marks. The two-headed Austrian eagle with a 2 for Vienna on chest but without the "republican" hammer & sickle in claws was used from 1938 to March 1940 only as the primary proofmark. This dates the rifle to 1939 +/- a few months. The NPv is still the Vienna Nitro proof mark. Besides these two marks there should be the year of proof marked too, as 39., maybe covered by the wood. The inscription "Waffenfabrik Steyr" is unusual too, as it was used after the "Anschluss" 1938 only. Since 1934 the official name of the combine was "Steyr-Daimler-Puch AG", but the M-Sch rifles were still marked with the familiar old name "Oesterr.Waffenfabr.-Ges.Steyr" = "Austrian Arms Factory Company Steyr". My .37 proofed M-Sch m1910 is still marked such, as is my .34 m1925. After the "Anschluss" they not only marked their rifles "Made in Germany", but left off the hint to past Oesterreich = Austria.
