This Eastman Kodak item seems to fit in a pocket (note the clip). The dial on the front "Made in the USA Eastman Kodak Rochester NY 4 4.5 5 6 7 8 10 12 15 25 50 *infinity symbol*"
It has an eyepiece through which you can see a filter. When you turn the dial on the front, the numbers on the gauge can be seen inside. It seems to be something you use to line up images. The bottom can be unscrewed - can it be attached to a camera for closeups?
Size & Material: black metal, silver metal; 3 inches long
