South Africa Wheatstone in Instrument Construction & Repair Posted February 8, 2019 2 hours ago, vdvzak said: That is a photo of the Wheatstone "Mayfair" reed board. Discussion here.... That's an interesting discussion. Did I understand correctly that May Fair instruments were made by Wheatstone's but sold under a different name? This instrument has a Wheatstone plate on it. I also read in that discussion that the value of a Mayfair is relatively low (maybe $600 15 years ago). I'm curious about this because I'm ultimately planning to sell it once my new concertina arrives, probably toward the end of the year. I bought it from the Button Box in 2014 for about $2,300, and while I've never visited the shop in person, they seem to be well-respected in the forums, and my impression is that they value things fairly.
