“Great running motor. It will need the carb cleaned. It’s been sitting in my shop for a while. It has a new radiator, gas tank, and seats. That’s what your paying for.
Comes with a second set of axles.
I think it’s a 1942 model off hand”

Has some updates.

“I have owned this jeep since 1967! Yes, that is correct 52 years! Did a rebuild with the original flat head 4, then modified in 1972 to a 307 Chevy V-8, 4 speed T90 manual trans, Hurst shifter, overdrive, CJ5 front and rear end. Still has drum brakes which work well. I would love to keep it (why not?!) but we are moving later this year and it’s time for her to find a new loving home. Runs great, current motor has approximately 15,000 miles on it.”

Looks ready for cruising.
