Thanks Jimmy J, figured you might see and weigh-in.
I guess it's just the case of something in the wrong case. Now we'll just have to wonder what it could belong with. 😊
*my Dad missed out on a 1926 Gibson PB-5 'ball-bearing' banjo some years back that Bernunzio had in on consignment. He had in mind for us to convert the original plectrum tenor neck to a five-string. Instead, the missed opportunity led to us designing a Style 5 inspired banjo of our own, with wood inlaid into wood on the back of the headstock.
