Lennox International (heating/cooling) has an advertisement using a vault door. “…we used a team of artists and muralists to transform a home into a money-saving vault.” For a Hollywood rendition it’s not too bad but they did get a few things wrong.

On the outside view, the hand wheel is shown to retract the pressure bars which is not how they work. On the inside view it’s reasonably close to something that could work. The pinions (small gears) are very large but could operate as shown. I believe the gearing shows 24 bolts, a traditional number, but the actual bolt protrusions don’t line up! It looks like there might be 20 or 22 bolts around the outside which is not possible if there are 24 inside the support ring.
