I saw an accordion the other day,it looked like a Cajun accordion with the 4 stops but the bellows was in 2 sections with a solid piece in the middle and the stops are a bit different, 2 with the melody, one tuned slightly wet, one an octave above and one tuned a third high, i.e. if you play a C note it plays an E just above it. Anyone seen one of these, it has no name on it and belongs to someone else so I couldn't take it apart and check it out. It had the spoon-type buttons on the bass side like the Hohner 114 and was a C accordion.
