Looks like a good setup.

This appears to be sitting on some kind of jeep chassis-turned trailer?.

“I have a 1942 Hobart welder. On a custom made trailer, a Willie’s motor and it welds great but has a loose wire connection. The trailer is worth 1000 by itself no loballers”

UPDATE: As of July 13, 2021, this GPW APU is now in Stefan’s hands in Germany. As you can see, by the time he acquired it parts had already been removed (see original post from 2017 at the bottom of this post). He does not want the APU parts. I figured it is a long shot, but that I would check to see if anyone had an interest in the APU-related parts (some are O.E. Szekely); Stefan is willing to part with them. Comment below if interested or email me at d@deilers.com and I’ll connect you with Stefan.
Here’s how the jeep looked prior to pulling the parts:
Here are the parts related to the PTO:

This looks in good shape.

“Up for sale is a Hobart welder that’s on a trailer, uses a gas Willies engine? Everything works great and is good to go.”
Update sold: was $700.
Runs.
“Vintage Hobart gas powered welder. Powered by Jeep Willys engine.
It’s probably 1950’s era.
Runs and welds perfect. Comes with leads and mounted on a trailer. Located at 3519 Edison Way, Menlo Park.”
This undated Siebert Willys Ambulance brochure was probably produced in 1954-or 1955, based on the grille design on page 4. There is no form number on it. Within the brochure the company describes three different ambulance options.
Derek provides more information on the Siebert Ambulances and has additional pics on the CJ-3B page.
Still works.

UPDATE: **SOLD** Was $375.
Looks like an early 1950s l-head. Seller describes it as diesel, but I doubt that.
“It is a willys diesel motor needs a 6 volt battery to start needs some cleaning and paint photos will tell all .Someone told me it is the motor that the army uses for jeeps I would think it would have to be dependable.”
UPDAATE: **SOLD** Was $20.
The Seller has more than one for sale. I imagine these are pretty rare?
“Vintage King-Seeley V54S-126D governor from Willys industrial engines. New in the box. Several available at $20 each.
