An acquaintance of mine has recently come into possession of a fretless banjo with the neck stamped William Avery Turner, London. I am trying to get some information for him about the banjo but know nothing of Mr. Turner. I would particularly like to know if he was the maker or did someone else make them. It looks like a nice basic instrument from the photos he sent and I hope to get a chance to examine it in person before too long. Thanks for any responses.
