Transversal scale

So it "was" used to identify and create units of measurement on other products? I looked it up on wikipedia, more clarification would be lovely!

Thank you so much for helping me identify it, too! No one I asked has a clue what it was or what it's used for. I assume it'a a depricated piece of equipment.

1.you take measurements with two-needled-thingy (slav here dunno word)
2.you put right needle on line on right scace (full units) so left needle is in the range of left scale
3. right needle now shows full integer values of (it's 10 on the picture)
4. you move two-needled-thingy up ot down to the moment when left needle points at slanted line.
5.you're between 5 and 6 on vertical scale so its 10+5
6.slant line is 5 so its 15+0.5
7 it's 1/3 between 5 and 6 so 15.5+0.03

Oh I kind of see, it's for making very very accurate measurements easier to measure? What about the other side with the C's?

Just because you are stupid doesn't mean you have to be an asshole.
