This RB-100 serial number 265601 started as a typical Style 100 with the 1/4" brass hoop. As is common beginning in the 60's this banjo had the "thin" multi-ply rim and has now been changed to a Cox 3-ply. The rim was fitted by Arthur Hatfield with one of his 20-hole tone rings and new Prucha hardware installed. The original resonator is the usual single bound and in great condition. It has 5th string spikes installed and ships in a hard case. If you have any questions or desire additional pictures, don't hesitate to ask. Thanks for looking!
