The Leslie 710 is a two-speed, 90-watt solid state two channel model (bi-amp: 40-watt treble & 50-watt bass) with a 15" speaker, a V1 Jensen V21 horn driver with rotating horn lens, two 6X9" stationary speakers, and a RotoSonic drum with a 6X9 speaker.
It has a 9-pin input to connect to various Hammond organ models as well as other brands.
Entire upper section is exactly the same as in a model 122/147/770.
Frequently, the Leslie 710 is modified to operate with single-channel a Hammond organ, as this one has been, with a Trek II LCO-1A electronic crossover ($81 value).

The speaker sits on steel base with coaster wheels.
Also included in a 25” 9-pin cable ($100 value), a Dr.
Fishsticks controller (AC power and 1/4" plug audio-in) with a 2-button foot switch to control the two speed rotation ($130 value).
I have been repairing and refurbishing this Leslie: the horn and the lower rotary need some lubrication - both top and lower motor run fine at both speeds but struggle to turn the horn/drum.
But I have another Leslie and don't want to work on this any more.
Parted-out there are probably about >$600 worth of parts, including rotating horn, Jensen V21, two 2-speed motors, 15" speaker, etc.
