That is a might pretty little travel dulcimer. Ron builds nice instruments. Wish you the best if finding it a new loving home.
Lil' Willie Dulcimer
This practice/travel dulcimer has 24 3/4" VSL with overall length of 29 5/8". The width is 1 1/2", box depth is 1", total depth is 1 3/4". Handcrafted by Ron Gibson. He began making a few of these with the idea of a quiet dulcimer that was small enough to carry on airplanes and be played in hotels without being too loud. (I learned this after conversing with Ron via email.)
Asking $175 obo. I estimate shipping to be $15-$20 via USPS Ground Advantage.
