Antique Iron Center Punch C-Clamp Shaped
This is a nice clean iron C shaped center punch with two adjustment on center. It appears to have once had other interchangeable pins at one time that most likely would fit into the thread compartment seen in the picture, there was none in it when found. The black paint is about 90% intact, shiny and clean, all the thread are in good working order including the cap. It is not marked by the maker, but has raised cast lettering stating "PAT. APPL'D FOR" on one side. The pin size (for the interchangeable pins you may have or want to make) is .312". A really nice heavy duty sheet metal type center punch!
