Reply To: new project: adapting the C. Wheatstone "Symphonium"
The most interesting Wheatstone symphoniums are the 24 keys, 32 keys, and even 44 keys versions, because they have all the chromatics (The photos and description are online, on the concertina museum website http://www.concertinamuseum.com/cmusindex3.htm )
The only video I found was the one of the Boston Museum of fine arts

Did you say you saw other symphonium videos? Are these videos online on the net? And where could I watch these?
