Thanks guys I have been in contact with the button box and I am awaiting a call back from Jim (might have the name wrong) he’s away till the 9th
I was going to list my concertina on Ebay next week and see what happens
As for keeping grandpas concertina I am! Just not the Wheatstone 31987 I will be restoring his back up I believe it’s a Wheatstone as well but maybe you guys will help with that J
This is the one as kids my two sibling’s and myself played with and by the condition its in we must have had a heck of a time with it but I’m sure the Button box will be able to restore it
