I was at a local historical tourist sight, Bowens Mills, and they had a mountain man rendevous, and a hammer dulcimer club. One of the supporting musicians was playing a 12 string banjo. The sound was very unique. It looked like a 12 string guitar neck and a banjo body. Is this just something that someone "cobbled together" or is it an accepted instrument with a history?

All the best,

Mick
