Hi,I love collecting old instruments, which I then actively use in my music. I was lucky enough to come across an Anglo concertina in a local flea market a couple of years ago. All the keys worked, and sounded almost perfectly in tune. It cost 35 pounds. It has no indication of brand. I recently opened it to let it air a bit and inspect the reeds (one had dropped a little due to some tarnishing), and I found this written in pencil inside:"Repaired by P.A. Groff, Berkeley CA July 1990"
I was curious if I could locate P.A. Groff, and so I found this forum where presumably with the same P.A. Groff as a member. I thought it would be cool to show it and I would love to get some idea of the possible origins of the concertina, just for my curiosity.
