I am a retired professor of marine geology, and now make concertinas, both Anglo and English, as a hobby. I am also well involved in traditional folk music. With partner Cate, I perform at folk gatherings, singing mainly sea songs and shantys using concertina accompaniment.
David...I would like to see your concertinas one day when I get into Hobart. I like the end-plate design, particularly the wide-mouth Tasmanian Tiger!!
