Clinton's "Plain L1 & R1" Model
If you didn't check the serial numbers you'd be inclined to think that this model was a very early developmental form of Equisonant - but the serial numbers in the 4900's are closer to the highest we've found. Was this perhaps a cut-down economical student model, or had Clinton found an easier way to achieve his goals? Clearly we need to find out.
