I was goofing with you, Melissa. All you need to do is look where the "0" on the 1/128th scale up top lines up with the 1/16" scale on the ruler. So you can see, for the Pelt, the "0" lines up between the 13/16" and 14/16", so I would say that one is just shy of 7/8". For the Alley, the "0" lines up between the 15/16" and 1" marks so I would say that one is just shy of 1".
Forget about the 1/128" - it's way too precise for marbles. Heck, manufacturers accuracy was barely under 1/16".
