Gibson Five-String Banjo

This banjo was made by Gibson, Inc. in Kalamazoo, Michigan around 1950-1953. It is a Five-String Banjo, style RB-100, marked #7075-4, with a maple shell, neck, and resonator, sunburst finish on the back (the neck may have been refinished as it doesn’t appear to have the same sunburst finish), rosewood fingerboard with pearl position dots, 24 brackets, 2:1 Grover tuners, and a friction fifth-string peg. The peghead shape is unique to style 00 banjos. There is no tone ring or brass hoop but only a bead turned in the top of the rim to serve as a bearing for the head. Silkscreened on peghead:
