Tom shared this M-38 that is supposed to be rust free (though it has some slight surface rust. Still, it’s worth a look.

“For sale is my 1952 Willys M38 (military jeep). The top is a factory “Arctic Top” that was installed when new. The Jeep was originally in the military then was purchased by the forest service and they painted it forest service green. This jeep has almost no rust on it whatsoever! Floors, body, hat channels are all completely solid and rust free. Some stuff was modernized: 12v converted/solid state distributor/standard fuel pump but I have all of the original 24v waterproof distributor/plugs/wires/pump. Lots of new parts, radiator was rebuilt, new fuel tank, seats. All gauges work like they’re supposed to. The Jeep runs and drives great and I drive it regularly. It has a clean Ga title in my name”
