Univex Mercury II Model CX 7 This is a rectangular metalThe Mercury II is a unique 35mm half frame camera that uses a movie camera style rotary shutter, partly housed inside of that distinctive top panel hump. It has shutter speeds from 1 20s to 1 1000s (plus B and T) and a scale focusing 35mm f3. 5 Tricor lens. Cosmetic condition is decent, with some surface oxidation on the aluminum body, no dents or scrapes. Function is good! A neat camera in good working over.
