You guys are sniffing around the answer, and, in fact, have figured out bits and pieces.

So, let's make this a little easier, by adding the missing piece.

See? It's just so bloody obvious now, right?

Are you sure you weren't playing "hide the pencil", Fishmugger?

I want to know what the scale/units are on that square in the upper right.

Fishmugger - this thing was designed for guys like you. All the fiddly work is done, you just need to understand how it works and where to find your entry arguments. And by "how it works" I mean moving the dials and rules, not the underlying math.

No algegra, trig, or calculus required. The eggheads did that already, and that's embodied in the inter-relationships of the various rules and graphs and dial.

I don't know what it is but it would be nice if it was an Obomber meter for dropping a load on congress. Or a seismic intensifier to break the left coast off and send it out to sea. Anyway, I wasn't there the day we covered that in algebra. I was playing drop the pencil.

Sill holding the three axis idea, The card looks like its set for a specific charge (M/S) so Im guessing temp. humidity and bore wear corrections.

Now that added bit makes it all clear.
That is obviously a device used by the graphic arts department in developing the "next-gen" cammie pattern.

Stumped but working on it. Well, I *will* be working on it when I get home from church. If Heath hasn't already nailed it.

The Wehrmacht did indeed use 105mm guns during WWII, it was their standard divisional gun.

The gizmo is a mechanical maker-of-calculations.

But not the ones you are driving at.

10.5cm=105mm. I can't recall if Herman used 105s in WWII, so that might make it post-war, Bundeswehr issue.

Ballistic caluculator for a 105mm howitzer?
