General Supply Willys-Powered Compressor Muskegon, MI $350

• CATEGORIES: Industrial-Welder-Generator

Could be worth a look. Some General Supply/Hesse history.

“This is a Willy’s Go Devil engine. This is an engine that has a conversion kit on it to make it into an air compressor. The engine is stuck, not blown up! The generator is missing also the air tank, air gauge, and fuel tank. I put some trans fluid in all of the cylinders about five months ago. The block is not cracked! It was built between 1945-1955. If you are restoring a Willy’s Jeep and need a engine this would work well for that.
I just don’t have the time to work on it right now, so I would rather re-home it than let it sit and collect dust any longer.”

General Supply & Hesse Compressor History

• CATEGORIES: Features, Industrial-Welder-Generator

UPDATE: Thanks to Brett, I’ve added some photos of a later model General Supply V4 (possibly a Ford V4) at the bottom of the post. 

Rick Webb shared what he knows about the history of General Supply Compressors & Hesse Compressors. His father Paul Webb played a principle role in the compressor’s development. I’ve included pics below to show how much alike they looked.

For reference, this is a General Supply GS-250 Compressor powered by an L-head. More pics here:


Contrast the one above with this one, a Hesse Horney Compressor powered by an L-head. More pics here:


Rick began, After reading information on youtube and the forums it seems as though there are a lot of questions concerning the hesse hornet and the gs-260 air compressors.I don’t claim to have all the answers however I can shed some light on the development of these units.

My father, Paul Web, lost his dad at the young age of 24 and took a job at the General Supply and Leasing Company in Kansas City, Missouri, in 1951 as a delivery driver. A division of the McDowell Tire Company, General Supply sold tire changing equipment.

When he took the job he met a man by the name of Dick Roberts who was an engineer. They soon hired a man with the last name of Simes (pronounced “Sims”) whose first name I do not recall.Simes was from Arkansas and was a self taught mechanic. He could not read or write, so they taught him to sign his name so he could cash his paycheck. He never used a torque wrench; however when his engines were tested his torque specs were spot on.

Hobart DC Welder Alexandria, VA **Status Unknown**

UPDATE: **Status Unknown** Was $300.

(02/04/2015) Gas tank leaks, but still may be a good price.

“Hobart DC welder from the 50s powered by an industrial 4 cylinder CJ2A Willys flat head engine . 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 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. Item being removed from a period transport trailer.”

Fire / Willys-powered Unit George, WA $2500

Its an interesting piece.

“For sale is a pull behind Willys Power Unit. It had a fire pump on the back which has been removed and sold. You can buy it and put another pump on the back, or a generator or an air compressor or???  The engine itself is a 4 cylinder Willys. It’s hasn’t ran in years but it DOES turn over. Since the pump has been sold ahead of it, I AM willing to sell just the engine if you’re not interested in the whole thing. $2500 for the whole thing or $2300 for just the engine. You remove AND haul. ”

Hobart Welder Snohomish, WA **SOLD**

• CATEGORIES: Industrial-Welder-Generator

UPDATE: **SOLD** Was $300.

It runs, but needs some work. May be a good price.

“Hobart Gas Engine Driven welder generator. Will need some work to make run but does run and work. Currently the engine cover is off and the radiator was removed to be replaced. Have new radiator and needs to be reassembled. Gas in tank is likely bad from sitting. With some work you can have a decent running older welder generator. Or use the parts for something else.
The engine is a cool old JEEP Willys industrial motor.
AS is no trades. The welder head alone will fetch $300 worth of scrap copper at the recycle yard, I would just rather see it go to someone who has the time to use it.”
