Oddly, I still have my trusty line gauge (pica stick, em ruler, etc.) from a long ago era when we used Linotypes to generate the text and then manually laid out the pages before photographing them for the actual printing process. Not a trace of computers in the process. And yes, 1 em was 1 pica was 12 pts was the way the sizes were stated. I never managed to use the agate measurement running down the center of the gauge. Also, this was prior to the computer folks redefining 72 pts as 1 inch instead of the 72.27 pts used in the typesetting business.
