This object has a three sided iron alloy base. On the base is a track which mounts a small frame holding a metal plate. The metal plate rotates 360 degrees within its frame. Beside the track is a primary arm which extends vertically.
The primary arm holds a double prism box above the metal plate. The prism box has four ports extending from it.
Attached to the other side of the primary arm there is a secondary arm which extends vertically, currently set at a roughly 45 degree angle. The secondary arm holds a lens with eyepiece and dials. This is suspended above the prism box.
On the other side of the secondary arm there is a convex rule. The convex rule has a lens, supported by a third arm, which travels freely along its radius.
