Thanks for the great info, Melodica-Me. I’ve also been hoping to find a Hohner melodica-model list and chronology like this one for their accordions: http://ebookbrowsee.net/med-00006364-1264085468-hohner-akkordeon-modelle-06-2006-pdf-d59308261 . So far no luck. I did get one of the HM-32s NOS from Hohner USA. Great tone, but seems to take way more air than the Yamaha P-32D. How many keys in the Cassotto?
