i believe folkcraft bought folkroots out some years ago and continued to make the folkroot instruments.

Folkcraft has produced a Folkroot model for at least a couple years.  Dulcimers come up on Shopgoodwill quite a bit.  But no one there can answer any questions about the instrument, and shipping is invariably expensive.  Good luck with your purchase.  Once you have it, you can contact Michael Rugg and get complete info on when it was build, woods, etc....
