Piston and rod removed from a 3HP Associated hit & Miss engine. Piston diameter is just under 4 1/2. Wrist pin and bushing seems good. No breaks or welds that i can see. There is a few “nicks” and scratches on the piston skirt but I don’t see it being to big of a issue for a engine that’s over 100 years old. Please see pictures for the absolute best description.
