I feel that I must put in a plug for my old friend Chris Harvey, who made the bowed psaltery that I have used since 1974 and also several superb Appalachian Dulcimers for friends in Germany and England (my own dulcimer was made by George Bowden in Mallorca).
Chris has retired to the depths of the Suffolk (UK) countryside and is occupying his time by making not only psalteries and dulcimers, but also Octave Mandolas and his update on the dancing dolls immortalised in the song "Seth Davey" and elsewhere. We have a couple that he made some years ago, and they are excellent, although we have always found the tune of "Seth Davey" too slow to make them dance properly - they really need a step dance or morris tune to get going!
Chris has created a website to advertise his wares, and you can even watch a video clip of each of his several types of doll in action.
