This concertina has been soldType : Anglo
Make : Lachenal
Model : 20 Key in D/A
Price : £575
Almost all Lachenal 20 keys are in C/G. Very rarely do you see the other options-Bb/F, Ab/Eb or G/D. You almost never see one in D/A -which means that it is higher than a normal C/G. The only time I have ever seen it before was on one of the semi-miniature 5" instruments. It is a powerful key and quite bright.
This is a typical rosewood-ended model with the finer fretwork , steel reeds and 5 fold bellows.
It has been fitted with new pads, valves and tuned to concert pitch. It plays and looks well.
If you could use a 20 key in these keys-get it quickly as you are unlikely to find another one!
