I really wonder how much the thing has been shot! The barrel stamp is CYY, indicating an April, 1952 date of manufacture. The SN is 208XX. According to a moderator at the Remington Society Forum, April 1952 was probably the first month the M760 was chambered in 300 Savage.
Being D&Ted for a scope might bum some guys out, but was perfect for me. I am not a collector and hunt with all my rifles. Since my eyes will no longer tolerate iron sights, the scope was welcome.
