I’m curious if anyone knows the historical model used for Martin Doyle’s keyless flutes or if they are of his own design. At our Wednesday night session, I was comparing a friend’s Doyle with my recently acquired McGee Metzler keyless and they appeared nearly identical in length, hole spacing, and hole size.
Michael- what is the diameter of your Metzler at the foot end of the body? my Doyle is “large-ish” at about 14mm where the body-foot joint would be. for comparison see http://mcgee-flutes.com/bores.htm.
