I recently aquired an old regoletta 20 button concertina.
The buttons keep getting cocked in the holes. on examination there is some soft tubing under the buttons that is supposed to keep them in line , but has dried out and is beginning to give out to where the guides on the bottom of the buttons just slide around on the lever.
Is there a source for replacement buttons, or tubing for under these buttons, or will gum rubber tubing , or clear vinyl tube, or possibly teflon fuel line tubing work?
Thanks--------RL
