My husband and I are interested in selling his grandfather's MacCann Duet. This C. Wheatstone ebony Aeola has 56 buttons, and ivory thumb rests. Metal rivet tags are also still in great condition. The piece was manufactured in London and was first sold December 22nd, 1922 according to the ledger on this link http://www.horniman.info/DKNSARC/SD01/PAGES/D1P1820S.HTM. The instrument also comes with it's original hard leather case. This instrument is playable out of the box but could use some TLC as some of the reeds seem to stick. Reasonable offers will be considered, but we are hoping around $2500. We are located in Maryland, USA, near Baltimore. I'd be willing to ship to any USA location with insurance. Outside the US would require more research.
