Does anyone make a window conversion for a 1951 Ford?

This old picture shows what looks to be a one piece rear side window and it appears factory, plus the car doesn't look to be a coupe. Looks like a rubber trim around the rear window. Was there a cheaper sedan that came with rear windows that didn't roll down?

 

I think it's a regular Tudor sedan with two piece glass. There's "something" not quite right about the photo, like it was cut and pasted, but only in the rear side window area. The rear corner looks lower than the front 2/3's of the window.

Without wing windows back there how are the kids in the back supposed to smoke??

 

When I blew it up I see what your talking about where the back of the window area looks odd. I found the picture on the Vintage Pictures from Days Gone By thread, post number 87612, and thought it might have been some odd body style Ford, something like the 55-57 Chevy business coupes with fixed rear windows.
