From March 13, 1938 to April 1945 Austria was part of Hitler's 3rd Reich,hence the inscriptions "Made in Germany" and "Waffenfabrik Steyr". Of course German rulings were to be followed by Steyr too. The German 1940 proof law required, for the first time, all guns being marked with the cartridge designation instead of model numbers or cryptic bore dimensions. So Steyrcalled their old proprietary 6.5 and 8mm cartridges Normal to tell them apart from the "high velocity" chamberings of the M1925, where they stamped "8x60 Magnum" even in the years before.There ought to be German eagle/N proofmarks and a proof date below the woodline too.
The stock of this rifle with higher comb and more curved pistol grip already resembles the later M1950 design. The sliding tang safety is certainly an aftermarket addition. The parted foreend seems to be a quite well repaired GI duffle cut. Note that Steyr used the old-style bolt-stop on M1903 actions up to 1945. They had to put the new, rectangular design on the long-cartridge models 1924 and 25 because they had to open up bolt travel to the rear. The old bolt-stop design would have ended up with it's rear end hanging out in the air, so they had to change the design to mount the spring in front of the bolt stop cut in the receiver.
