My friend lives in Littlestown, Pa. The overall exterior condition of metal is 50% blue with the balance turning to patina/gray, no visable exterior rust/pits. Wood is solid but with lots of dings, no cracks. Bore & chamber are bright & clean with strong rifling, no pitting.
Since I don't know if surplus 8MM is corrosive or not I suggested if he wanted to shoot it he should use moden 8MM until I can research the Ammo more.
It's not like he's gonna shoot it much anyway. He's 85 yrs old....Thanks for your post!!...Mike Haas
