The rotor in this case is a cube representing azimuth - the angle between North, measured clockwise around the observer's horizon, and a celestial body (sun, moon). Hence, the presence of both "N" and "E" compass directions on the rotor.
The gimbals denote "elevation" and "roll."
Interesting piece which serves as both scientific tool and modernist decorative object.
Very good, vintage condition with patina/light wear to the aluminum, as shown.
