Not a clue of maker. Nice workmanship. Interesting design take on the modern, not traditional dulcimer design. Not having a 6+ fret doesn't make it an older build. There's a guitar builder guy turned dulcimer maker, on one of the FB groups recently, who was all upset when I suggested his $800 new-made dulcimers would more likely sell of they included the 6+ fret and did not include French polished finish. He had no clue what the 6+ fret was -- he'd followed one of the old building booksbooks.
Obviously this instrument is only good for ball-end strings, with those tail pockets. The tuners are pretty common covered singles still made today. The head and tail aren't carved, just bandsawed to shape with the edges rounded over.
