I think many of us started out with a mass-produced Hohner & learned a bit on it — moved easily:   but got dissatisfied with its rather 'buzzy' accordionish tone & looked around for something more characteristically concertina-toned — you all know what I mean. I repeat I am glad I happened on the wooden-ended Lachenal for my own [mainly for accompaniment] purposes — even if some of you won't believe that I like to play melody in the left hand! & I am not even left-handed btw...
