This is an anglo concertina, a "ceili" model made by the Button Box, R. Morse and Co, of Amherst Ma. I do the woodworking on these instruments, everything except for the fretwork, which is laser-cut. Excellent quality concertinas were made on a production scale by several firms in London from the mid 1800's until the 1930's, but their popularity faded, and the industry never recovered after the war. Concertinas experienced a revival in the seventies and demand for excellent quality instruments has since far outstripped supply. Currently fewer than ten makers each make 5-20 excellent quality concertinas a year, with up to five year waiting lists. The Button Box instruments are the best quality concertinas made on a production scale (they've sold over 150 in the last three years) since the 30's, and the most serious concertina building effort ever this side of the Atlantic. I also play the anglo concertina myself, (every Sunday night at the Irish music session in Greenfield, MA), and I'm very proud to be involved in their production. Follow this link to the Button Box web site. Or this link to Concertina.net, for lots more on these great instruments. Try Frank Edgley for custom-made to order concertinas, and his own music and tutors. Finally I've attached a link to Irish concertina master Noel Hill playing tunes.
