As Group44XJS said 32 volt units used coil ignition. The 110 volt units were magneto fired. The 32 volt model numbers were 15C3 and 15C33. looks like both of yours are 32 volt.

If it is 110 DC, a normal battery set would be 55-2 volt individual lead acid cells, plus 4 or 5 reserve cells. In the day, 110V units were nearly twice the price of 32V because of the number of cells to make up the battery.
Your 12 volt car battery has 6 cells.

But that doesn't mean you need an entire bank of batteries to start it. I have a large Lister 110V genset (See my avatar) that I start with 3 lawn & garden batteries, or you can hand crank. Just disconnect when it starts to fire up. Either method will require a magneto or an isolated ignition set up.

At that point you can run any 110 DC appliance or anything with a universal motor. Regular "old style" incandescent light bulbs or an electric heater if it doesn't have a non-universal fan setup.

Attached is a page from a 1927 Graybar (Western Electric) catalogue showing battery prices.

I guess some things have never changed, batteries always have been and always will be EXPENSIVE!!

The 140 volt Kohler used 56 cells for a nominal system voltage of 112. A normal operating range would likely be 108 ~ 120. Though I'd expect that the voltage would seldom exceed ~130 during charging, I have always wondered what, if anything, was done to protect the lamps at the higher voltage encountered during charging. Tapping the battery is not a viable option, unless special care is taken to charge the extra cells individually.

If we used today's typical off grid settings that many cells would bulk charge at 136 volts.

That's a beautiful machine there, Steve!

It seems that in the "old days" cells were charged to an even higher voltage of 2-1/2. So from standard nominal battery voltages of 6, 12, 32, and 112, generator voltages of 7-1/2, 15, 40, and 140 result.

I thought I would give a little update. Sorry for the delay, I have been busy at work lately. I disassembled and inspected a month ago and determined it needed new rings, rod bushings and valve guides.

Making new valve guides. It has an unusual valve guide where it is a blind hole and the guide is driven in and seats about a half inch from the bottom of the head. The original guids were made from some type of fiber material.
