I have a 1947 year model 70 just like your 257 Bob but mine is in 30 Gov't 06 caliber. When I bought it, it was in even better condition than your beautiful 257. The key word in the last statement is "was". For the last 32 years I have drug that rifle over countless miles, killed more deer, elk, antelope and coyotes than I had a licenses for. It is scared up, with the checkering beaten flat, bluing missing and what looks like a polished bolt knob. That knob got polished from use. Every dent and ding tell a story.
