A common problem I had with these was for the inner and outer wheels to move when the combination had not been changed. The really fine teeth did not hold the 2 sections very well. If you stuck the key in but forgot to turn it, you could still turn the dial! Who would do that you ask? Government employees (at least then) have to change their own combinations. Like all things, if you don't do it often memory fades. I put on probably 100 of these locks. I replaced every one of them. They were not made for the rigors of this world!

So does anyone know what did they did for combination locks?
