I think that the motor is a synchronous motor but no start winding.
I have not studied the theory of the different "stops" yet on how they
modify the signal from the tone wheels.
Mine has a really poor finish. Bad veneer. Not sure if I am ever going to
do something with it or not.

My folks had a big Hammond that we sold with the estate sale after my
father passed away. I think we had it since around 1967, and sold it
around 2003. It had a whole "start up" procedure, where you had to run a
starter motor for so many seconds before you turned on the main motor. I
think this was because the main motor had a flywheel that it couldn't
spin from a dead stop.
The family was kind of surprised at how much the bids went up on it, as
I gather it had become somewhat of a collector's item.

I worked for Warwick Electronics in 1974-1975. They made TV sets for
Sears and Kmart, and owned Thomas Organ which owned the rights and
manufactured the Moog Synthesizer.
My responsibilities were on the TV side, but think I saw the schematics
once and I'm pretty sure it was a 100% analog design. No computers, beeps,
or boops.
Hammond was the one that used tonewheels to generate the frequencies and
harmonics. Still no computers. Motors.
Apparently now lots of things go bing-bing-bing:

Probably wouldn't work today.
The Moog was invented when the first computers were leaking the beeps and
boops. Today's computers are so well shielded that it would have made the
invention of the Moog Synthesizer non-intuitive.

My first lab standard was 1 one pound bar of a mixture of lead and
babbit I found in our farm shop.
I cast it and hammered it and shaved it until it weighed the same as a
pint of water.
I then took it through a metal detector at an airport.
This was right after DB Cooper and it was the first metal detector at
PDX.
I was certain that it could not detect non ferrous metals. I was right.
Told the kids at school, the teacher called BS and I bought the bar to
school. Teacher still called BS.
But in those days teachers told me things like "when an atomic reactor
operates, it gives off particles. They collect those particles in a
container. Atomic bombs are those containers and they break them open
when they want to unleash the bomb". Another gem from the same
(science) teacher "when computers operate they make beeps and boops.
Some figured out how to make those beeps and boops in a controlled
fashion and that is what a Moog synthesizer is".

Heat actually doesn't rise.
Hot air or liquid will rise due to lower density, assuming it is free
to rise while denser fluids sink. So it might be true in a flooded
battery but not an AGM battery.
Also not true:
A pint's a pound.
Ground is ground the world around.
Lightning never strikes the same place twice.
Can't even trust righty tighty lefty loosey, witness twist ties on
stuff from China and even some Cat5 cable.

It probably would depend on the enclosure and/or whether there is
insulation around the rest of the battery. If the battery has an
insulation blanket around it, the heat from the heat mat should
propagate through the entire battery. Heat does rise.

If you get those heater mats under the battery will you have a
temperature gradient where the battery is warmer on the bottom than
the top? Will that hurt anything?
Suppose the charger has a temperature probe as well. My instinct is
to tape it to the same top post as the thermostat probe. I figure the
lead post tells me more about the temp inside the battery, and if
they're on the same post then the charger and heater are working off
the same assumption. Is that reasonable or would you do it differently?
I may be at risk of fussing over details that don't matter much, but
it's in my nature I guess.
