Time to repost this.
This is essentially a high-end best-period Lachenal MacCann Duet with a slightly modified (Chidley) layout so that the pattern is uniform throughout by consistently repeating in all octaves rather than shifting in the upper octave. The difference is minor overall, but wonderful if you appreciate a fully isomorphic layout as I do. A notation chart is in the PDF, herewith.
The concertina is in excellent condition with original glass buttons.
In Summary:Vintage Lachenal
65b MacCann Duet in modified Chidley layout
Cry Baby and Whistle
Leather Wrist Straps
The original case in poor, but serviceable, condition as one would expect.
I really do want to send this along to someone else who will appreciate it.
Post-op prognosis renders it surplus.
Please see the PDF, herewith, for photos, evaluation and documentation of work performed by Wim Wakker, and the previously mentioned notation chart.
