Welcome to the campfire. It's amazing how many of us start out finding this place because we inherit an heirloom.
Rebluing is optional, up to you. I hunt a 1945 99EG in 300 Savage that's totally gray. It's got character, and has killed a whole bunch of deer. I don't feel bad about carrying it at all.
