May even be someone I should know (or someone here!), but I don’t Just an “out of interest” question, I’m not thinking of buying. Certainly looks nicely made.
I did a Google search which came up with no hits for “windwork” with either flute, irish or polymer as the second word. It’s hard to tell from the photo, but it looks like a cyclindrical rather and a conical bore. Craftsmanship, at least from the photos, looks good.
I guess the ultimate answer is - no, I’ve never heard of these flutes.
