When equipment is orfered on a Corps of Engineers contract, it will have a brass Engineers Data Plate attached to it stating the Nomenclature, DOD and manufacturers specs.
There were Hobart Generators in WWII, Chrysler industrial Powered would be in the 300Amp range. They are nice as long as they still function, but 99% of the parts are no longer available thru Hobart, once the governor and vacuum controla fail, it may as well be junk. If the engine has under 1000 hours and it runs smooth, the engine is a good candidate for a WC.
