Those or very nice rifles, especially the carbine. I once had
a 1952 model in .308. Sold it to a man in West Memphis. The
classic stock, like on your rifle, is my favorite. The 1956 model had the ugliest stock ever put on a M-S, my opinion of course.
It had monte carlo type buttstock with severely scooped out cheek piece. Like you, I wanted a 6.5 cal but never found one in
a condition that suited me. Congratulations on the find.
