I don’t know how vintage this is, but it looks like it’s never been assembled.
“Winneco Palmer Plastics 1/35 US Army Willys Jeep. I had no idea Palmer Plastics did WWII military kits until this item crossed my desk. It’s complete and unstarted with all parts still sealed in the factory polybag. Decals (a bit age-yellowed) and instructions are both included.”
