" Looks nearly unused ". This is just speculation on my part; the fellow I got it from had been a work friend for 10 yrs and he retired 5 yrs before I did. About 2 yrs after he retired,he started divesting himself of stuff and called me and gifted me the anvil and a bunch of odd tools. He had been a Navy aircraft mechanic CPO in his earlier life. If he had used it during that type work I can see how little damage would be done, working primarily on aluminum, sheet metal, etc. Turns out he was dying and knew it hence he started cleaning house. Good guy, he is missed.
Oh yeah, one of the things I got from him was a small mini anvil, made from a small piece of RR rail, crude but cute. I'll find it and post a pic when I do.
