This is the original Leslie, a single speed cabinet with no provision for remote control.  This photo comes from an old organ / Leslie computability guide.

The model 30A was made specifically for the balanced output of a Hammond "G-G" Console (IE Model B or C).

Unlike later models, the horn in this cabinet was made of paper mache' and spoke through the top of the cabinet instead of through louvers on the sides.*

Unlike later cabinets, this cabinet featured ELECTRO-dynamic speakers.  What this means is that BOTH speakers do not have permanent magnets, like speakers have today, but rather a large coil of wire which acted as an electromagnet.  This coil was also wired in such away that is acted as a filter choke for the amplifier's power supply
