First of all, Hello. I'm Mark 996 and I'm brand new to this. I inherited a 30 button "Regoletta" Concertina from my grandmother. It looks like new but I noticed that some of the buttons would disappear when pushed. When I took it apart I saw that all the little rubber tubing used to hold the buttons in place was dried and crumbling.
I tried to replace it with clear plastic tubing but it was way too stiff. Do I use surgical rubber tubing? It seems to measure 5mm outside and maybe 3mm inside. I can't be sure. Also would anyone know the approx. worth. There was a Concertina "Regoletta"
With 20 buttons going for $329.00?? Thanks to anyone who can help Mark Occhipinti
