The Imperial Cubex IV was distributed in c1964. It used 127 roll film that produced 4x4cm exposures. It is a plastic camera that was manufactured in the USA by Herbert George Camera under the Imperial name. It is a simple and inexpensive square shaped snapshot camera made of plastic. As the name suggests it was specially made to accommodate the square Flashcube flashbulbs of the time. A Boy Scout Cubex IV version was also made displaying the Boy Scout logo on the front. It featured a built-in viewfinder, a fixed focus IMPAR 47mm lens, and a front snapshot lever. The back of the camera prompts you to advance both the flashcube plus film after each exposure and a separate wheel is supplied for both. The Flashcube work best at 4 to 9 feet (1.25 to 2.7m) with color film and 4 to 15 feet (1.25 to 4.5m) with B&W. When new the camera came with a wrist strap enclosed inside the camera, instruction booklet, and a warranty registration postcard you filled out and sent in (stamp not included). The Cubex IV used two AAA batteries for the flash that are stored in a compartment on the top middle of the camera with a pull-up battery holder separate from the lid or top. It also has an eject lever for the flashcube, a frame view window in the back cover, and an optical viewfinder.
