Here's the deal and why I was always taught and practiced to utilize higher (better yet 3 phase) motor voltages where possible.
Its true Watts still = Volts x Amps regardless if you operate at 120 or 240 and you cant create or destroy energy, only change its form. For one thing if you run higher voltage and therefore less amperage you waste less energy in the form of I Squared R Heat Losses in conductors. The R is the same so if I is less, I squared is wayyyyyyyyyy less. A part of the energy goes to heat versus to turn the motor which is the work you want to accomplish when you pay for the energy instead of it being lost as heat.
Motors are obviously NOT perfect devices, not all the energy in is = to the energy the rotating shaft can provide, some of is heat. Energy in must equal energy out, its just that the less you waste as heat in all the conductors the better off you are.

To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
