I have tried to get S&W to reblue and color casehardening, but they refuse to work on old guns.
They seem to have cut off period of about 1955 that they will do such work on.
Don't really need to case hardened, guess coloring with hot torch would probably be the right way to go, but such coloring will wear off from handling so I'm told.
Once had a Savage M99 take-down rifle lever color heated and it turned out really nice...but cannot remember the guys name or address in Cody Wy from about 15 years ago.
I don't know why more people don't do such restoring for old guns, seems like there's a lot of gents who would like to have it done.
Thank you for you're reply.
Note: the attached photo beautiful grips and color case hardening are not my firearm, but I have one with the same type grips but in 75 % condition. Only showed this to exemplify hammer and trigger...plus the purty grips.
