The tiny but excellent "Bell Brand" tailpiece. These tailpieces were standard issue on several banjo ukes including: Avalons, Gretsch, and others. Grooved for 5 strings, but no worry, just use the outer four and you are in business. Very easy to string because a single knot slips inside the grooved area and leaves them tidy and without any string ends to scratch your arms and snag your tuxedo. These were 1 1/16" wide and sat on the tension ring for a nice pressure angle downward from the bridge. This gives good contact for the bridge to the skin and provides resonance.
