30 button Ab/Eb Jeffries STILL for sale, as the prospective buyer has apparently sailed off the edge of the earth. An absolutely beautiful concertina...e-mail me if interested..

I can vouch for the fact that this is a really terrific concertina, and it sounds great, a real Jeffries sound, in the Ab/Eb tessitura. (I wish I could afford it).
