This vintage RB-100 has been converted to a flathead with a Tennessee 20 tone ring. Originally from the factory, this 1964 style 100 would have the 1/4 inch brass hoop along with its mahogany neck and maple resonator. This one definitely has some patina and vintage mojo along with classic flathead power. A few of the hooks and nuts have been changed to more modern ones at some point along with holes being filled from previous cam tuner installation. This Banjo also has upgraded Rickard Cyclone tuners and ships and hard case. If you have any questions or desire, additional pictures, don’t hesitate to ask. Thanks for looking.
