The mill were I went for a load of sawdust for the mushroom project has had this gen tucked away, It's a Hobart generator not sure what the engine is.
http://www.ewillys.com/2013/03/26/1942-hobart-generator-willsboro-ny-ebay/I do know its a gasoline engine and it still turns over, I purchased it for $50.00, has some interesting instruments on the control panel.
his M5 generator was built for the US Army in World War II, by the Hobart manufacturing Company.
It is built on intergrated steel skids. The generator has a four cylinder ZXB Hercules engine.
From online research, this engine was sometimes used in the Willys Overland Jeep.
The output of the generator set can be field set for either single or three phase operation. The output is rated at three kilowatts.
This unit has sat for many years, but I believe can be rebuilt to operate correctly, and could be used as a functioning display. Just to make clear, the unit does not run at this time. T
his unit is rare today, and from research, provided electrical power for the BOFERS anti-aircraft gun setups in WWII. I have found similar generators for you to look at on you tube, but I have not been able to download a link due to ebay rules. Type in M5 generator on the you tube search bar.”
