This is a very neat side x side percussion pistol shotgun, about 58 caliber or 20 gauge. This has 13” barrels with platinum breach plugs and barrel bands. The barrels are Damascus and the triggerguard, side locks, top tang and fore end ramrod guide are engraved. The ramrod has an augur tip. The mechanical function is very good and is tight and sound. This is an interesting and unusual piece.
