I have a small Mandolin Banjo. The rim is only six and a half inches, edge to edge with five and a half inch diameter skin. This sits in a two and a quarter inch wooden bowl that has a one inch raised center button at the back. The headstock is plain, slightly tapered. I can't find any name, lettering or numbers. Though it is an inexpensively built instrument,it is in fair condition. It is a bit difficult to tune due to cheap gearing. The round, untapered knobs on the tuners are a marbly brown colour. I suspect it might be a GH&S I haven't heard of one like described.

Does any one know of this one.
