Both of those FM engines are from between the wars (6 spoke flywheels) and the smaller was also built in England up until the mid 50s, to compete with the Ruston (insert 2nd name depending on what week you're talking about) engines.
I was given a Rathbun Jones engine built by Ingersoll Rand in 1905, provided I moved it from the building it was in. The roof removal and replacement, rigging and hauling was prohibitive, and despite the fact that it was older than one the Smithsonian was also acquiring at the same time, it got broken up for scrap.
That generator is a GE and was probably 2300 volt based on the engine speed, and being directly coupled. The exciter alone would power a few houses.
Go find me some Crocker Wheeler bipolar dynamos. I'll drive out for them. Size is all relative.
