The Mastermatic 330 was a fixed focus camera manufactured in Allemagne Germany in the 1970s and used 126 sealed film cartridges. It has a Steinheil-Cassarit Color-objektiv 45mm lens and a selenium meter that adjusts the aperture accordingly. It also features a Flash Cube socket that does a ¼ turn to the next flashbulb, a film view window in the back cover for frame counting, optical viewfinder, a battery compartment for two AAA batteries in the bottom of the camera, a right thumb film advance wheel, and a large shutter release button on the side of the lens assembly. Interesting fact: 126 film cartridges were made by other companies besides Kodak. One of them was Triple-Print film labs from Philadelphia, Pennsylvania in the 1970s and they sold Triple color print film with photofinishing. For each negative, the user received a large photo and two mini photos. The “triple print” was a promotion to mail your film and get 3 prints per negative mailed back to you for a nominal fee. Another finisher with the same deal was Jet Age Service, also from Philadelphia, Pennsylvania but at a different address.
