Emailed the guy about his ebay box - see link.
I pointed out that he had posted photos of two different accordions. he told me that he had in fact two accordions. I asked him which then was he selling, the dark timber one or the light timber one. He told me that he's selling the dark timber one first and then the light timber one in about a month. They're both keyed in C Sharp.
Glad that's cleared that up. Get your bids in now. He wants $3500 for the box.
Apparently Randy Vidrine Charivari and Lafayette Rhythm Devils fame likes to sing against a C# box, so Jono had a C# box and Mitch tuned his fiddle a half-step down rather than the usual whole step.
Anyway, I seem to remember Jono telling this to me, but it was several years ago.
