It's a quadrant as far as I can tell. Used for taking angular measurements of altitude in astronomy and navigation.
German ...
To me, it looks like part(s) of an artillery Fire Direction Control set to determine directions for pointing indirect fire weapons systems.

It's a protractor, but I have no idea what the specific use is...
Post a close up of the manufacturers markings and I'm sure it will be easy to narrow down.

Is it maybe a Sextant?
It’s a paperweight

A sextant has 60 degrees. A quadrant has 90 degrees. This is a quadrant.

Angle gauge for setting the sporadic mandragular brackets on a '62-1/2 Thripps Special with sports suspension.
It looks like a protractor with changeable scales. I used a protractor and scale for drawing pictures of parcels of real property from the legal description.
44specialfan is correct! The hook at the corner of the L is placed over a pin in your map showing your battery’s location. Another pin marks the target. Swing the long arm read the range then line it up with map north. Use the protractor to read deflection (direction) for the gun. Powder charge is determined by the range to target. A manual is used to determine the elevation for that powder charge and range to target. In Vietnam, we used the Fire direction computer FADAC along with the manual plotting. The data had to match before it was sent to the gun.
The various arms are each calibrated for different projectiles since HE, smoke, illumination, etc have different trajectories. I believe this device is for an 81mm or 4.2 inch mortar.
My job as FO was to call the mission and to adjust fire on the target.

Now that we have it all figured out I can cut the cheese charges and we can go for a 20 round fire for effect.

Now that brings back memories!!!!!!!!!!!!!!!!
I was Army Artillery before I was Navy Intelligence.
And I don't remember that device from way back when but if you say it's for artillery fine by me!

It was used for mortar fire for Indirect Fire Infantryman or 11C, which was the MOS assigned.
I also did 4 years with the Four-Deuce in exotic locations like Fort Stewart, GA, Camp Casey Korea and the beautiful Fort Riley, KS.
Fort Stewart had a range where you could see your mortar fire hit your target area. Pretty cool.

remember the quadrant from Ft. Sill 1966
I had AIT at Ft. Sill Oklahoma in summer 1966. We trained on the 105's but after AIT, the Army had me stay there and complete 10 weeks at the NCO Academy and I recall the quadrant as shown by above posters being the subject of some fairly intensive math classes during that "Kiwi Kollege".
About the only memory that does stick with me of Ft. Sill (other than those best forgotten of downtown Lawton), is of the morning rides out to the range in deuce and a half's towing 105 behind us and seeing those "seas" of tarantulas crossing the road...so many it looked like water in the distance, or a mirage...but you knew when you started hearing the crunches then could see for yourself!

Gee, if one actually looks at the pic it is clearly stamped for 4.2” mortar.
