reverb springs torsional vs longitudinal

[Bissell, Harry]

Michael Bacich is correct, the unit I saw was in a tone cabinet, not the
organ itself. It was about 3 to 3 1/2 feet in length, with a "space frame"
covered in a velvet dustcover (Looks ? Sound ?) I saud to myself "What the
hell is this thing?"  and lifted the cover. Voila reverb spring. The cabinet
was in an old college auditorium, mounted in a hidden room above the stage.
The loudspeakers had field coil magnets (electromagnets). A roommate wanted
to "liberate" the speakers to play guitar through, but I assured him that he
didn't want to carry a DC supply to make them work. Sometimes the field
coils were used as a choke for the DC power supply. I'd guess Michael is
right about a 1940's date (but not 50's)  Harry Bissell :-)
