Hesse Hornet Air Compressor **SOLD**

• CATEGORIES: Features, Industrial-Welder-Generator

UPDATE: **SOLD** Was on eBay.

This is a little confusing. Seller calls this a CJ-6A engine, but the tag reads CJ-3A. It’s a flathead, so the CJ-6A designation seems incorrect.





“For sale is a 1963 Hesse Hornet compressor made by the Hesse Carriage Co. It was designed to sit in the back of a pick-up or on it’s own small trailer. This particular Hesse uses a rare Jeep Kaiser 4cyl CJ-6A engine. It pumps air by having two of the 4 cylinders blocked off to compress while the other two function normally. The engine itself looks good and runs great. It may need a small tune-up from storage but nothing major. It does not come with a battery or gas tank. I tested it by rigging up a temporary tank.

It runs and generates.

“World War 2 military generator made by Onan. It comes mounted to the trailer and with a vintage wing tank for extra fuel. It is powered by a Willys jeep motor. The generator was bought surplus after the war by the Elgin Amateur Radio Society and they used it for years. The motor runs good with a fresh tune and LOF.

Hobart Welder Alexandria, VA $450

• CATEGORIES: Industrial-Welder-Generator

This might be worth a look.

“Hobart DC welder from the 50s powered by a 4 cylinder CJ2A jeep flat head engine and mounted on a 2 wheel trailer that fits Chrysler rims. Item has been stored in a garage for around 25 years after being taken out of service due to a leaky gas tank. The cables were scrapped due to the insulation all falling off of them years ago. The trailer tongue has a single hole in a flat strap cut with a gas torch.
The engine is stuck from sitting for years but should not have gotten any water in it.
I have a key for it that fits the switch and moves between positions.”

1944 Signal Corps Power Unit New Jersey **SOLD**

• CATEGORIES: Industrial-Welder-Generator

UPDATE: Was $300. **SOLD**

This Willys powered power unit has potential.

“Vintage 1944 WWII aircraft generator. This generator was running 10 years ago. Currently turns over, but we have not tried to start it. Has been dry garage stored for 30+ years.

Four cylinder Jeep Willy’s engine capable of generating 120V, and also 400Hz. There is a separate Chrysler starter motor (attached to flywheel) that can be hooked to a 6V battery for easy starting. A small hand crank for starting is also included.

It is a 2.5kW 400Hz aircraft generator, but has been modified for 120v 60Hz output on one outlet.

We do not have any manuals or paperwork for this unit. The manual is available via:
The manual is: TM 11-975 Power Unit PU-35/U (17 November 1944); 53 pages, 28 illus.

Dimensions on this unit are 47″ length x 22″ width x 38″ height. It is on small metal wheels. This would easily fit on a small trailer. A winch and set of ramps with careful management of the generator could be possible for one individual. It is very heavy though!

If this ad is posted, the generator is available. More photos available on request. Cash upon pickup.”

Empire Tractor Marlow, OK **SOLD**

• CATEGORIES: Features, Industrial-Welder-Generator • TAGS: .

UPDATE: **SOLD** Was $650.

Finding an Empire Tractor is a rarity. Carl and I are finishing up a special post about them for eWillys sometime in May.

“Interesting little Empire tractor. These were built from left over Jeep and Willy’s parts from WWII. For the best source of information go to – this one is almost complete, the engine, drive train, etc, is there. It’s missing some of the body/panels. Great project or if someone is restoring a 40’s/50’s Jeep or Willy’s, lots of good parts! $650 cash.”

US Navy Generator and Ronk Transfer Switch Quincy, CA $1900

• CATEGORIES: Industrial-Welder-Generator

Blaine forwarded this ad.

“Generator is a U. S. Navy World War II era unit powered by a original Willy’s Jeep four cylinder engine. The Generator was manufactured by O;Keefe and Merrit. It appears to be a PE-95G 10 KW and is designated a U. S. Navy N-15. It will provide 120 or 240 Volts at 60 hertz. It is started by using the exciter field of the generator and not a separate engine starter. Most of these generators saw little use during WWII but were used extensively in the Korean and Vietnam wars. A unit almost identical to this one showed up on the TV show Mash in one episode. Own a piece of history!

Generator has two brand new 12 volt batteries. Also included so that one can operate “off the grid” or have a ready source to power a home or anything else is a:

RONK 7205A 200 Amp Meter-right Transfer Switch that list new for about $800 It does not appear to have had any use.

1952 Trailer and Generator New Jersey $1900

• CATEGORIES: Industrial-Welder-Generator, trailer

Here’s a neat combo that Steve spotted.

“1952 Military Jeep Trailer with Onan 5K Generator. This unit kept my house running for three weeks after Super Storm Sandy struck. Ran everything in my house. It struggled with the electric dryer. The generator is made to last forever. Electric start and even has a hand crank for an emergency. Large fuel tank was nice because it would run all day on one tank full and then all night on another tank full of gas. The trailer is solid with no rust. Tires are in good condition. I built a canopy to keep the rain and snow out and it is easily removed. There are multiple 110 outlets around the trailer and one 240/30 amp to connect to my house. There is also a circuit panel. The trailer was garage kept from 1952 to 2009. Contact Martin @ 908-50seven-054five.”
