Saw a film a while ago, can`t remember title or who was in it but it involved a bank robbery where the manager was forced to divulge the combination to the outer doors of the vault and the hero produced two very nice shiny black S&G dials and pushed them onto the shafts to dial open the outer doors. Is this a common thing? or was the detached dial thing just a plot device? The whole thing got a bit silly when the wall next to the main vault door (timelocked) was breached with a few rounds from a 20mm cannon at point blank range. The robbers were all right though, they had protective goggles!!! Wot a crock....
