The Brownie Twin 20 is another simple camera from Kodak which was manufactured from 1959-1964, Like many Kodak cameras of this vintage, it was designed to take size 620 film, producing 6x6 negatives. I assume the "twin" comes from the two different viewfinders the camera is equipped with. It has both a waist level finder and a regular eye-level finder. There are three exposure setting that provide some control over exposure, and the lens can be focused to three different settings, the typical close-up, group portrait, and landscape distances seen on many basic cameras..
Both finders have bright-lines that at first glance I assumed marked the edges of the frame. However, the manual indicates that the bright-lines are meant to be used for making "super slides". For those who don't know super slides are 4x4cm in size, these are large slides that could fit into a regular slide projector designed for 35mm film (35mm film projectors were and still are significantly cheaper than medium format projectors). Larger slides should produce better images since they would not need to be enlarged as much as smaller 35mm frames.
SInce 620 film is no longer available, I take the film off regular 120 size reels and respool it onto the thinner 620 spools. This is usually a simple operation but this time I messed up and didn't wind it tight enough, resulting in some major light leaks on the first couple frames, as well as burning in some frame numbers from the backing paper. Oh well.
