26 Button Lachenal, steel reeds, wooden ends, new seven-fold bellows and a complete overhaul and tuning by Button Box. This instrument has an unusually sweet sound, and good karma to boot, as it has been played in many a Chicago session alongside some great musicians. If you want a traditional vintage concertina in very good shape, and you aren't worried about four extra buttons that you don't need anyway, this may be the box for you.
This concertina was listed on the Button Box website for 2,400. I'm selling it here for 1,700 with a Button Box case. I live in Chicago if anyone wants to stop by and try it out.
