I just wondered if anyone out there could direct me to someone who can put a value on my Concertina. It's a Lachenal around 1900s according to the serial #.
its c/g 20 button. Excellent condition , recently replaced: Wrist straps, pads, valves.
tuned etc plays lovely with original case

I would appreciate any ball park estimates or help in this area etc.

Thanks

Without knowing where you are I can't suggest who would be a good dealer to talk to. Have a look at the Shops and Dealers section of the Concertina FAQ, link in the sig block below.
