Old Gun Guy,
If you have time, I would like to have a private conversation with you - I want to restore some old pistols and even possibly a few old rifles. I would like your advice as to how to remove pits and rust from the surface metal, what kinds of costs you had in restoring these pieces? I know parts are available. Do you bother restoring pieces with bad bores? (I don't plan to, in those cases I plan on replacing the barrel). Overall, how do you think that the cold bluing will stand up over time?
These photos of the pieces you have restored are beautiful. You do some very nice work. You should offer your expertise as a service for people who want pieces restored. You would get paid for it, get to take pictures of the pieces, they just wouldn't be in your collection
