I was digging around in mt desk drawer a few minutes ago looking for something (that I did not find), and came across this:
When I bought this back in the day, I figured that I was really walking in tall cotton.

I keep one of those along with my pocket stereoscope and Army issue lensatic compas in my briefcase at all times. You never know when you may need them. That is along with my 6" K&E Slide Rule and manual. Does that make me wierd ?
No weirder than the rest of us!
:good:
I knew it was a drafting tool.....took me a few minutes to figure out its purpose. My manual drafting was limited to a year in high school and half a semester in college. Never ran across one of those until today.
This view "gives it away" so to speak:
Cool, a proportional divider.
It's a fancy schmancy way to replace the graduated rubber band.:-)
Not sure of the official title, but it sure helps when plotting topo by hand (for contours)! Of course, the aforementioned rubber band works, and if you have drafted enough by hand, you don't need either!
Cool! But what I really noticed was the HP 41CX calculator. We still have, and still use one.
It is a collapsible hair comb for draftsmen....or draftswomen.
or a badly designed back scratcher for the same.

My stable (all work fine):
41C (semi-retired)
41CV (ditto)
41CX (used daily)
41CX (used weekly)
41CX (Ready Reserve)
And by “daily,” I mean constantly!

BINGO!
Glad you knew the proper name Dave, it was not coming back to me.
I spent many hours with mine, but never had a a fancy case. Yes, I still have (and use) mine.
YUP...that's the correct name (at least that's what I always called it)!
I guess Dave gets extra credit on that one.

Got any spare "feet"?

I wish!
My orignal 41c is missing one, and my daily user is missing 2 (cause I lost one, and removed the other so it wouldn't "rock").

Some on eBay... $4.50 for a new set of 4.
I can explain it to you, but I can't understand it for you...

I could never push myself to the reverse input. I did use a calculator daily until I learned Excel. I've closed traversed in the past. 3 wire level loops work great. I now use the calculator for a few checks, it is usually buried and hard to find.

me too, Excel is a wonderful way to to do calculations.
