Got it home, and actually not hard to figure out how to disassemble. It had a small amount of fine rust from the benign neglect suffered from never being cleaned. It's a good thing too, as one of the grip screws were slightly boogered up, but not too bad. Barrel looks great, it was just dustier than all get out. Nipples were beat to all get out, but didn't show any carbon on the part that's on the inside of the cylinder. I suspect that it's only been dry fired, but can't be sure.
