RE:Did you check the photos?

R:" but I doubt if you'd sell such a thing."
RE: I am not selling anything, not even the ideas. It is all free for my part!
It costs less than £20 and a couple of hour's work ( if being a little bit handy) to applicate the "ergonomic" handle concept to any model concertina

"Good luck though, and let us know when you've built it".
RE: As I said, the handles are there, just to be used...

R:"PS. I can't really imagine that many people are going to start doing serious surgery to their cherished instruments"
RE: You obviously have not looked at the photos. My handles are fixated by three of the end bolts and NO "surgery" is done..!They don't even touch the endplate.

R:" so this whole conversation, although interesting, is actually pointless. And I doubt that you would persuade any of the existing makers (the few who are left) to take up the idea. They're all to busy making boxes that people want!"
RE: I bet they would make whatever handles you want if asked and paid for...and mutually understood that they improve music making...
