Waidmannsheil. I acquired recently a MS Model 1924 in 9.3x62; I don't have yet the rifle, which is still under process off being imported to France. It has a ribbed barrel, and the original owner's name as well as '1937'are engraved on the rib; this rifle bears the Vienna proof house mark, but I don't know the proofing year as I have not disassembled it yet.
