When EBarnacle asked "When did reeds start getting glued in?" I got the impression that s/he had experienced only "good" concertinas. My first Anglo was an Italian job, white perloid laminex and 20 big black accordion buttons on the outside, with accordion reed frames attached (with wax) to reed blocks exactly as in accordions. Some wouldn't dignify it with the term "concertina" but it got me styarted and there are a few of them around.

But you're right, I've never heard of reeds being "glued" into place.
