This antique metal hand held priming and de-priming tool is for the 12 gauge shotshell and is in very good condition retaining 92% original chrome finish with the balance as a darker brown patina. This tool is stamped "12" on the top handle and "CHAS. EUTEBROUK / PAT. JUNE 5 1877" on the left side flat. Mechanically this tool appears to function perfectly. A nice quality antique hand held reloading tool.
