The Argus Instant Load 164 started being produced in 1968 and ended in 1969 after Sylvania was sold and camera production was suspended. Sylvania owned Argus 10 years at that time. The camera weighs 4.6 ounces and is 4"x2"x2.5". It takes 126 Cartridge film and uses flash cubes that advance with the frame wheel. The flash cube mount is powered by two PX825 batteries that are housed in the film compartment. The PX825 battery is no longer available but replacements do exist. Frames are advanced with a right thumb wheel that also loads the shutter. The camera also has a ¼” by 20 thread tripod mount, optical viewfinder, film view window that shows the frame number, and has a handy carry strap. The 164 was one of the last of the Instant Load series and the cheapest. The Instant Load in the name denotes the ease of film change with 126 cartridge film. This is a point and shoot camera that is closer to a Box camera than cameras of that era.
