These "pass-boxes" were pretty much indestructible. The (24/7) hospital I worked for installed this same kind in the walls between the darkroom and each x-ray exam room in 1970. We slammed the metal film cassettes (holders) into them with great force as that was the only way to let the person inside know that there was film to develop. Thirty six years later we switched to digital imaging (no film) and the pass-boxes were still in good shape with virtually no visible damage and very little loss of paint. The only service I recall them needing was the occasional tightening of the screw that held the handle on.
I agree with Matthew M. This is not a tomography machine. The tomography machine I worked on in the late 1970's didn't have a ceiling mount so that the arm holding the x-ray tube could swing back and forth.
This is a general x-ray table for any exam where the patient needs to lie down. My clinic replaced one similar to this just four years ago. It was replaced only because we went "digital" (no film).
The room above is likely a darkroom for developing x-rays. The metal frames hanging on the wall had clips in the four corners to hold the film in place while it was dipped in the developer, fixer, and water baths. Then the frames were hung in a dryer for 20-30 minutes. To get a "wet reading" the radiologist looked at the images before they went into the dryer (usually for emergencies). The machine below the frames looks like the tanks that held the chemicals.
About a year ago I was lucky enough to tour the inside of the crypt of one of Milwaukee's (WI) beer barons/brewing families. The outside is very impresssive. Again, not quite as large as the one above, but still very ornate.
The inside though was dissappointing. Just plain white marble.
No ornamentation nor carvings. No statues nor stained glass. In retrospect, I guess this is actually very practical --- after all, how often does one open the family crypt to the public?
