I am a sucker for an estate sale, although I do still feel a little vulture-ish. Found this neat little tool for $2
It can:
open letters
six inch ruler/90mM
measure angles
back side has 1/8" and 1/4" to foot scale drawing ruler
table of fraction to decimal equiv. *in 64th's* 0 to 1inch
However, it has one feature I can't figure, what am I missing here?
In the arc of the fold-out, on the inside of the arc it has 0 to 180 degrees
on the outside of the arc on the main body, it's marked 1 to 5 with .5 subdivisons - what is this used to measure?

A product of eastern KY public schools, you probably heard the 'swoosh' as anything about radians went completely over my head.
Let's see, from the internetz...one radian = 57.29 degrees...
Interesting thought but not sure that's it. With the measuring lever all the way in, the 0 degrees is same as the 0 on the 1 to 5 scale. And the 5 is just about right across from 43 degrees.
So you get points for being much more awake during math class than I, but not sure that's it.
It seems so incredibly simple, like I'm missing something, but I just can't figure it.
Here is a better close up with the angle lever folded in.

It is a goniometer. I have a few.
Re: Estate Sale, "The Executive Desk Chum", and a question
The photo makes it quite clear. It is, in fact, a Vernier scale, dividing the 5 degree segments of the main scale into single degrees.
Griz was correct.
I don't know how I missed the post before mine.

There you go. You read it like the old school micrometers or calipers, looking for the one measurement that's not offset.
Guess I've been using all the new fancy digital readouts ones so much now it didn't occur to me.
It's still a fascinating old desk/measurement tool.
