Thank you to Unique Master Models (UMM) for generously providing an excellent tool for "field testing."  Thank you as well to the IPMS Reviewer Corps for letting me be an evaluator.

The jig is akin to an adjustable protractor with a range of 0 to 180 degrees.  The base plate is metallic blue metal with white, etched tick marks and numbers marked in 1 degree increments.  A polished bar is screwed to the base plate at the zero position and an adjustable or positionable bar with a set screw can be locked between 0 and 180 degrees.  Both plates are 3/16 in thick and project up from the base plate about 7/16 in.  I checked the indicated angles on the jig with other tools and the angles match the precision of the jig, in other words, the angles on the jig are pretty darn good!  The setscrew on the positionable plate held well and did not slip when the jig was dropped from about 5 feet onto a carpeted floor.

The jig is designed to assist in gluing parts together at precise and repeatable angles.  Replicated multiple glue-ups at the same angle can be very frustrating.  With the easily set and held jig angles, coupled with stout plates for clamping, churning out many identical parts is much more precise.  If the part to be replicated is small enough to go on the jig, the angle could be set using the original, and the resulting "measured" angle be used to directly produce duplicates.

I recommend this neat jig for both improving glue-up precision and reducing frustration.  There are many possible uses.  I did not experiment with compound angles, but I believe this jig could also be used to good effect by using some shims to "tilt" the pieces for gluing in the jig.

Thanks you again to UMM and the IMPS Reviewer Corps!
