OK just stripped the bolt, the cocking piece, firing pin, safety are all parked in what I call WWII green same as receiver , and marked with an R the bolt sleeve is parked the same color but of course is stamped with a G for smith corona. the cutoff lever is marked R and blued, every other part of this rifle has an R stamped on it somewhere, even the spring for the handguard has an R on it, now is it worth it for me to replace the sleeve , safety, and cocking piece to be all correct or is it good enough.
