Well, my guess (and Martin Ryan's) in the original thread was right.

There are a couple of pictures of Andy in David Kettlewell's book about the hammered dulcimer, All The Tunes That Ever There Were, the title being a quote from Andy, who said 'You can play all the tunes that ever there were on the dulcimer'; see http://dulcimer.new-renaissance.com/.

Andy Dowling died in 1991 at the age of 92.
