You started a prior thread (which appeared linked below for me in the “Related” section) about a prop from the 1944 film An American Romance possibly being re-used 24 years later as the EVA pod in 2001. Here’s the turret from the very end of An American Romance:
Here’s the EVA pod from 2001:
They’re both pods with a circular window and two horizontal things on the front (folded on the EVA), but other than that pretty different. Plus, according to the Wikipedia article on the film, the turret wasn’t a prop–An American Romance ends with footage from of an actual B-17 airplane being assembled. You can see the turret in the end assembly line scene here (starting at 2:30).
That being said, it’s possible Kubrick or production designer Harry Lange were thinking of a ball turret when creating the EVA pod, or maybe they just arrived at a similar design organically.
