Has anyone done any estimates on the survival rates of different makes of concertina? I've not been able to find any references so far.
Are there a greater percentage of e.g. Concertinas made by Jefferies still around and being played than , say, Lachenal's or Jones?.
Given the extensive research and data collection being done by Dowright it may be possible in the fullness of time to extrapolate from those results for Lachenal's.
If anyone has come across any information please will you post the links or get in touch
Thanks
Mike
