In my research of Cold War locks, I have ended up on an interesting path into Cold War nuclear missile launch silos.
Remember those movies like Red Dawn and War Games, where they show a couple guys in berets and jumpsuits sliding around in office chairs in a small bunker?

Then they open a door and get out 2 keys and walk to seperate panels insert the keys, and turn at the same time to initiate the missile launch?
I'm trying to see if anyone here knows what brand those locks were, and if they were wafer, pin tumbler, double sided wafer, or something more exotic like a Maxis key.
here's a photo of such a panel from a Titan II silo.

"One of two keys used to launch Titan II. The keys had to be turned within two seconds of each other and for a total of five seconds in order to start the launch sequence."
Here is a photo of the key the commander had to turn, in order for missiles to accept instructions from the other 2 key panels. There is a patent number on that, maybe this will lead somewhere good.

If anyone has better pics of the key, key bitting, or cylinders, I'm interested in learning more.

and much googling..
Patent 3,035,433 (1962) Frank J. Testa, Inventor for Eagle Lock of Terryville Connecticuit, USA,
What an amazing sidewinder lock! the key had Scorpion CX-5 style cuts on one side, in which would ride knobs attached to wafer like things, and when all was alligned properly, including what looks like normal wafer key bitting, the sidebar was allowed to fall in and the lock could turn. sort of like an ASSA Desmo cam lock, or like I said the Scorpion CX-5.
large pics ahead..


akes Medeco's 1968 sidebar look less and less original by the minute..
