I need to liquidate part of my concertina collection for cash flow reasons (ouch). We just had a big move and also had a serious illness in the family where we had to personally pay for the treatments. If any one is searching for a particular instrument, let me know. I have maybe 30 concertinas to part with all the way from a 1839 Wheatstone prototype in perfect playing condition to a number of golden era top shelf Aeolas. Most are English, some duets, and a couple of entry level Anglos? There is a mixture of fully restored to untouched but all instruments are complete as I recall. Breaks my heart, but it is time to let them go.
