Always thought it had different sound and wouldn't have been a Gibson, although it sounded like a ball-bearing, whatever brand it was. Ran across these old photos and I'm thinking a Vega of some sort? I think someone will be able to ID it through prior knowledge, or by looking at the unique Flange.
Thanks, Brian. Followed the links and eventually read the story as reported by Marthy and as dictated by Eddie, of the "drop-kicked banjo." Couldn't stop laughing. While I was reading, all I kept thinking, was dear Lord, had we had cell phones in those days, what a video that would have been!
