Bob, Possibly George K. can tell us a lot more off the top of his head, but there was an "early" 321, then a "revised" 321, then the 321A (followed by B and C). Bill is right about the clarinet..in early versions it was "synthysized" from the Tibia, the late version derived Clarinet from the Great Main signal keyers, and had its own pre-amp. The 321A started with serial number 31284 (according to the S/M). If it has six TREM/Vibrato Tabs, then it is an A version, five it is a straight 321. four tabs it is a B or C. How many on yours?
