A week ago in another topic I asked : What is known about H.Boyd as a performer?
but I got no answer so I try to put the queston again here...
I had noticed a Lachenal price list from 1890s saying this:
"...characteristic features of the two latest models introduced by us. The Bowing Valves;
as used by Signor Alsepti, Messrs. J.P.Johnson, H.Boyd, J.Pirochnikoff, and other eminent artists, are helping to break down the prejudice against it amongst the most able musicians
of the present day."
So...is anything known about the "eminent artist" H.Boyd and were the bowing valves used at all ?
