hello all. this flint i got off of my dad this past fall. i found it in his attic while cleaning out his old house. he said to throw it out, but i just couldn't. he bought it as a kit back in the 70's but never fired it. when i found it, it was in bad shape. the barrel was all rusted, brass tarnished, and the stalk was unfinished. i brought it home, took it apart and cleaned her up. but i have no idea what it is. i don't even know the cal. but it looks like a 45.
