I have what seems to be a George Case concertina. Mother of Pearl inlay, silver capped buttons, riveted action, and identical to one in the George Case section of the Concertina Museum. The Action box is numbered 1212 , the Reed box 930 , and the bellows 910. In addition there is a date written on the inside of the bellows 24-12- 69. Christmas eve? The hand is fine nibbed and looks old. Are we talking 1869? I think so.
Can anyone help me date this or head me in the direction of finding out? I would be much obliged
Phillip
