Argus C3 Matchmatic
A very popular collectible made even more popular by its appearance in the 2nd Harry Potter movie.
This is just a cool camera, from its impressive dials and gears, to its nifty two-tone skin and bright chrome trim. This example is shown topped with the clip-on selenium meter.
Because of its shape (and weight), the Argus C3 is affectionately known as "The Brick".
Made from 1958-66.
