Peter,
Regarding the cartridge your rifle is chambered for, the marking 9x74.5 is not necessarily the nominal caliber. This marking was placed by the proofhouse and means the bore diameter(not groove or bullet diameter)was measured as 9mm. The chamber was long enough to accept some case 74.5mm long.Subject to your making a chamber cast and slugging the bore, I suspect the rifle is chambered for the currently avaliable 9.3x74R.

The crown/E stamp for a higher than "normal" pressure proof and the 15 gramm = 231gr bullet weight are easily explained by going to old catalogs: Your rifle was proofed for the then DWM high speed load: While the standard 9.3x74R load was (and is) a 18.5 g = 285gr rn bullet at 680 m/s = 2230 fps and then 2800 at pressure, the high speed load was a 15 g = 231 gr pointed boat tail bullet at 805 m/s = 2640 fps and 2950 at. Your rifle was proofed for the latter.
If 9/31 is indeed the proofdate September 1931, The change in spelling stogos - stogus is explainable too: Johann Stotz and Leopold Goessl opened shop in 1923. In 1927 the partnership ended, Stotz being sole owner, but he was in Troubles apparently. In 1930 the remains of the company was taken over by Wilhelm Knopf, who slightly changed the St&G mark, but kept it close to familiar. By 1939 Wilhelm Knopf had disappeared too.
The barrels of the rifle were supplied by the well known Suhl barrelmaker Wilhelm Kelber, W.K.Comment
