The Agfa Parat-I is a fixed-lens half-frame 35mm cameras introduced by Agfa in 1963. There are a total of three nearly visually identical cameras released in 1963 that use the Parat name with a few key differences: the Parat-I (no meter), the Paramat (fixed shutter speed, automatic aperture control), and the Optima-Parat (automatic exposure system, different lens options).
The Acro Model R is a relatively obscure World War II era rangefinder camera introduced in 1940 by the Acro Scientific Products Company of Chicago. Like Spartus, Acro was part of the “Chicago Cluster,” a group of Chicago-based camera brands that produced a series of nearly identical Bakelite cameras. However, unlike the vast majority of those cameras that were designed to be simple and cheaply made, the R is an upscale model for advanced amateurs.
