Unidentified Remote Combination Viewer Vaults

I've seen the first two images in the book Lure of the Lock (Holmes wrote that section), but I don't know where they were installed. The other two are interesting but are new to me.

I have worked on these doors for years . The right angle gear is the main problem with the combo lock. The pin in the gear loosens and move starts and it all down hill from there. The locks on these doors are on the wall behind the the viewing station. The door is locked with a rod system. The vault alarm is a vibration type. That hook up to a control that floods the vault room and area around the vault floor. thats the basic over view of that type of vault. TJ

Amazing mechanism shots you've posted there medeco, a complete first in terms of remote combo viewers I think, so a BIG thanks for posting those.

The outer unit with the bevel gears is pretty much exactly how I'd imagined it tbh, but the real shocker has been seeing the simplicity of the internal locking layout, theres a lot less in there than I'd imagined!

For those folks who have worked on Remote Combination Viewers, have you ever seen Patent Numbers on their interiors? If so, can you please post the patent number(s) - Thx!

Why are there large gaps between 100 and 0 on the combination dials? All combination dials are different except for the number gaps.

Note the WD40 in the foreground.

Thanks for this latest picture! Emergency doors often are "different but similar" to their big-brother main door. I like the two arrows that line up to show the locking lugs are aligned for closure. There are pins in the door like those in the main door. Both halves of the alarm contact can be seen. No surprise there is a beefy door stop. A data plate of some sort is on the lower hinge that has been painted over, demonstrating that this was not the original paint (if it was even painted at all in the first place). Was the central area was originally glass, replaced with metal at a later time when the glass broke?

All that dust makes me wonder if the door has even been closed recently. The greasy appearance of the door frame makes me want to grab that can of WD-40 and do some cleaning.
