Working model of National Archives vault - GIF and photo

[Toolmaker51]

Interesting design and that you posted this today. A friend just sent a picture of an 1880 bank vault with some impressive engineering for the day.

That vault door is just astounding, only example of 20 active bolts I've seen. And with all that engineering, the finishes topped it off; maybe damascening, certainly jeweling and engine turning, engraving, acid etching and perfectly fit moving parts. That time lock says Diebold to me.

And we miss PJs...again.
