Amont1,
Model E - Console organ with 25 note flat pedalboard ... makes for a good practice organ, although a flat pedalboard takes some getting used to, particularly if one has consistently played a 32 note concave one.
Value? I'll still go with $100 - $200 being reasonable on the open market. Some of those older organs were made better in lots of ways.
Next question just for curiosity: Tube type (1958 and earlier) or Transistorized (1959 and later)?
(btw, I changed the thread title - the only "electric" organ was the Hammond as it used rotating tone wheels for tone generation - Gulbransen's, Lowry's, Conn's, Allens, in the old days were all "electronic", as they used oscillators (capacitors & resistors, etc) for tone generation)
