GUEST,Everett, how could anyone help you identify your banjo
when you don't give any information, even the most basic?
You did imply that it was originally a four-string, converted
to five. But that's not at all helpful.
But is it open or closed back? What sort of neck and fingerboard
decoration, if it still has the original neck? What's the shape
of the tuning head, if original? Diameter of the drum? Any name ANYWHERE?
What sort of tuning machines does it have? The more details you give, the more likelihood of at least a fair guess.
