Does anyone know what locks are used on the vault?
My observations, from a visit a couple of years back, is that there are two locks of the same make. Both are lever locks with a double-bitted key. My guess is Rosengrens Tann (see here for a picture http://www.rosengrens.com/NR/exeres/5DEC47F0-1173-424A-BF8E-5B2FF32A2379.htm), although they may also be Kromer Protector. Anyone have more info?
(No I'm not planning to heist the Crown Jewels!
