Here is the information my friend provided:
"Bruce Henry was an industrial arts teacher. He made dulcimers on the side. His wife Lucy and he played at local historic and town festivals in the noter style. She taugh music in schools. Her main instrument...flute. They live in Montgomery which is over the river and mountain south of Williamsport. I presume they are both alive, but would be in their late 70s or somewhere in their 80s. I do not know if Bruce still makes instruments. I have found that his instruments nearly always need fret work to play well. The fret arrangement was in the traditional 7 fret to an octave. DAA or GCC tuning. He never placed a 6 1/2 fret on his instruments. I'd recommend keeping it that way and use the instrument for traditional noter style playing.
Just Google and find:
C. Bruce Henry, 85, of Montgomery, died Thursday, Aug. 8, 2013"
