Was it really a MS 1905? The 1905 magazine is too short for a .30-06 aka 7.62x63. I suspect it was a MS 1924 like mine, the rarest of all M-S models. The model 1924, called the Sequoia model in the USA, was the first M-S model with a longer magazine. It was chambered in .30-06 only. Made to a contract with the American importer Sequoia amounting to 1000 examples, these rifles were originally marked M.1924 on the receiver ring. Apparently the deal fell through as serial numbers end in the 500s range and many such rifles remained in stock in Austria. Subsequently Steyr sold them off at a 10% discount, along with their 1925 model. As the 1925 was the first M-S model offered in several calibers, 7x64 and 8x60S at first, the Steyr factory removed the M.1924 inscription and remarked the rifles KAL:7.62x63. Here are two photos of mine, Steyr serial number 299, "factory" mounted with a Kahles Heliavier 4x scope.
