This bayonet locket is attached to a bayonet leather scabbard to hold the bayonet scabbard to your double hanger, shoulder carriage or frog. We attach these to our scabbards before sewing the scabbard together. To attach the locket punch 2 holes in the leather then put the prongs through the leather and use to small washers or brass sheet metal and peen them on to the leather. Be careful peening as no to bend the prongs. These are made of solid brass and measure 1 3/4" long 5/16" wide.
