Thanks! - Yeah, I've seen this as well, but am starting to convince myself that may be a prototype (OR is the 1st year they were made) as the headstock is totally NOT like those pictures.
The only picture I've found is this:
The website where the pictures are reads: Two Gibson guitar banjos, both from 1918 which was, I believe, the first year that Gibson made banjos. One has a 12 inch pot and the other a 14" pot.
The one on the right is it, albeit the pictured one has a clear head, unlike the one I posted. The clear head is probably not the original.
I'm curious as to the value.
