I'm posting on behalf of a friend who has two concertinas for sale:
C Jeffries Anglo in Bb/F concert pitch, 39 buttons, metal ends and buttons. It's a very nice instrument that plays well. Would buy it myself, if I could afford it! See pictures.. Looking for £4000.
Lachenal Treble English Concertina, 48 buttons, wooden ends, metal buttons. Not sure about the reeds, but steel, I think. Can't really comment on how it plays, as I'm not an English concertina player, but seems in good playing order. £800.
Any questions (such as the "extra" buttons on the Jeffries, just ask. Hopefully the pictures should give you a reasonable idea.
