Restoring a $400 rifle for $250 doesn't sound like a great move
I was thinking more like $250 to restore a free rifle, but I wasn't thinking about the carrier assembly and cartiridge guide....... a $250 rebore may cost more than a $350 rebarrel.
Used scopes without grandpa's SS number are cheap enough. Engraving on butt plate is a $14 fix. Few hundred solves all problems except the SS on the action. They ain't making any more of them.
