    Another example of emergency doors yielding to ventilation fans, in this postcard sent in 1921. The bank is in Minneapolis at 730 Hennepin Avenue and is now City Place Lofts.

    The doors are by Mosler.

    I've identified the location as CFS Carp in Ontario, Canada, a cold-war bunker. See http://en.wikipedia.org/wiki/CFS_Carp as well as http://www.diefenbunker.ca and http://jenandwillsnorthamericanadven...fenbunker.html. In particular, the following image which also shows the vault has a passageway around it complete with mirrors, intended to foil burglars trying to break in through a wall. Why this is an issue at a cold-war bunker is not clear.

    And while we're at it, the main door (Mosler? Diebold? Taylor?):

    Why does the door in the botom left picture have a sign saying "do not touch without gloves" ?

    Sweat and oils from hands can be corrosive to a variety of metals and alloys. You can see the results of handling the door to the left of the time lock, and above: rusty, dark, stained metal. Since the site is now a museum, artifacts should be protected appropriately.

    Older doors (including day gates) often had handles made of wood, plastic, or other material, and bank managers were supposed to use them instead of the steel parts. This issue became less important as stainless steel came into use.

    Thanks for the swift and informative response. Odd how something that could withstand hours of attack from anything made from man can be scarred by naturally occuring body sweat !!!
