I just picked up this bad boy on Ebay. A Sargent and Greenleaf 6730 combination lock. The better S&G locks have a little knob on them which you turn when you are ready to open and this prevents any manipulation but this one allows the classic stethoscope wielding activities from the movies. Of course in reality you don't bother with a stethoscope and it normally requires a good couple of hours of graph drawing and wiggling. I only know the theory, this will be my first chance to actually try, at least when it arrives. Maybe tomorrow?
