When I was working in the communications centre in the Clyde Submarine Base 1982 to 1985, the three of us technicians had a safe for the confidential and secret handbooks.
The combination had to be changed every six months, and a copy of it was in a sealed envelope in the boss's safe. Each time the combination was changed, a new sealed envelope was done. The boss would open the "old" envelope and when you weren't looking, he would try the old combination to try to catch us out.
What we did was .......... Fred's birthday (and I still remember it after all these years) was 28th Oct 1950.
We set the combination to 28-10-50 ............ 00 at the end of course, then you turn the dial anticlockwise and the door opens.
Six months later, we went to 38-20-70, and six months after that, 48-30-80 etc etc
