All the '52 models pictured in the 1995 edition of the KFOC handbook have a two piece windsheild. All the '53s pictured are from rear or the side! It looks like the '53s have single piece windsheilds in them as no center bar is visible through the other windows or in reflections. The "How to know one when you see one" chart in the 1971 issue of Automobile Quarterly shows the 1952-54 Willys with a single piece windsheild. It's a hand rendering, not a photo and only one is shown with the caption "1952-54 Willys" under it. Hopefully someone can shed some more light.
