UPDATE: **SOLD** Was $12,500.
The seller notes that 1955 was the first year Warn offered the five-ring warn hubs. Actually, they (both the locking and the automatic hubs) were offered as early as 1953, according to at least two different ads.

“For sale or trade. I am gunsmith so primary interest is firearms but no harm in asking. This is a great Willys that can be driven just the way it is or you can pursue additional restoration. Everything works, 4×4, factory Warn hub locks (first year those were offered), overdrive, front and rear PTO with a winch on the front bumper. Dual fuels tanks. Older paint still looks good, just not shiny. Seats were all just rebuilt (foam and covering) in a canvas looking modern material. Less than 200 miles on a completely rebuilt and balanced Chevy L6 250 with MSD Distributor and Electronic Ignition. Starts and hums along very smoothly. Steering is vintage and next on my restore list if I keep it. Need $12500 in cash or trade value to consider parting with this fun rig.”
