Rare E.B. Mansfield fretless open back banjo. Lowered price. Patent 1872. Price reduced!!! See pictures and copy of US patent. Not many out there. I’ve only know of one other. A favorite in my collection but it’s time to sell a few. Plays great. I’ll link you all to YouTube video of it being played. About a 10 3/4 skin head. Adjusts from I’m bottom. Ebony Reproduction tailpiece. Friction tuners work well. (New real gut strings were $70,00) 1/2 in bridge.
