Forgot to mention: The M1950 does not have the blind sideplate on the left side of the receiver, intended for side mounting a scope. BTW, some funny thing happened at the Steyr factory from time to time: My own “Magnum” action in 6.5x68 was proofed in 1957. Though it is obviously a post-1952 action with side safety, sideplate and without clip guides, it is marked “Mod.1950”! See this old thread:
