The bottom one has a label inside, says 1939 copy of Savart's Trapezoid (orig. made in 1820). The top one looks like an experimental fantasy. It's the middle one that looks like a real antique, but the neck looks more like a guitar until you get to the head. ??
Fascinating. Do you have any other pictures? Or even a higher res version of that one? My email address works if you don't want to post to a site.
The middle one looks as if it is meant to be based on a dulcimer (note the flat fingerboard, the modal fret intervals higher up and the slots in the nut) but the piercings interest me. An American acoustical researcher and builder, Carleen Mayley Hutchins, used to experiment with apparently odd-ball piercings, blocking them up in different sequences to analize the way they altered the sound.
I have lots of half-finished acoustic experiments littered around the place so it's a person after my own heart, so to speak. Love to know more.
