It is hard to find these luthiers. Thanks Ken.
information on Arthur West and Henry C Dessler
i found West's obit. but no real information. He passed away in 2016. Apparently a Mountain View AR native. The one currently for sale on EBay certainly looks like a good example of 1980s dulcimer design and appears to be good craftsmanship.
Not a word on Henry C Desler, Dessler or Dressler
