the early fifties gun did not say mounty on the barrel, the gun should have a 23.5" called a 24 barrel, white spacer between the butplate and fluted stock and a black with white center plastic insert at the point you would attach a sling to the stock, the straight stock is the key there were only about 4300 built with the long barrel in 1953 as noted by the k prefixtallguy606 said:My K-prefix rifle I don't think is a Mountie. Doesn't say that on barrel. I had a later model Mountie once, and the barrel was shorter. I don't have rifle in front of me to measure, but barrel is not really carbine length. And the forearm is slim, not the "fat" style. It's got an old steel tube scope on it, looks like an old Weaver, but no info on tube that I can find. Turret looks like brass. I am selling some guns for my 84-year-old father in law and this may be one of them, can't decide whether to keep this or the Rem 241....he said, take your pick!
