Does anybody know where any of these are?

I don't think there is sufficient evidence from the photo to conclude that full sized reels would be obstructed ?

I just picked up a couple of similar mid sixties Ampex's. Large 5-in helical scan headwheel & offset reel heights. They have a solid Made-in-USA quality.
