Were these used in jeeps? It they were, I thought someone might find it interesting.

“You are bidding a Portable Generator with 2 cycle engine. Engine has compression and spark. Will need work to make it run. Complete unit with all parts. Has tool box with additional brushes and spare parts inside. Handles on two sides of engine for carrying. Might require 2 people to carry. Engine is 2 cycle but you must use 30W non detergent oil mixed with fuel. todays 2 cycle oil is not heavy enough for this equipement. Be warned because use of other oil or lighter oil will cause damage.

I believe it is a WWII Military generator used in aircraft and jeep radio’s or other application. Gauges and generator seem to be all complete and in good condition. These make a weird sound and are loud when running. Tank cap needs new part for pressure relief cap. Has primer. Generator is for radios and air craft machinary requiring 120 V 400HZ. Only lights can be used if not designed for 400 hz or an adapter to adjust the hz.Collector item.

Signal Corps Power Unit PU-6/TPS-1
Duel Voltage generator
Model 13A120D28-1
120Volt AC, 28 DC, 14.3 Amp

Looks to be in good condition for its age,
Will need some work to clean out the gas tank and carb
It is a 2 cycle engine with an aluminum gas tank so its not rusty.”
