I found my grandfathers old Argus C3 in his attic. It had been up there so long the copper on the leather case had oxidized. After opening it up it seemed like it was mostly clean inside so I figured whats the worst thing that could happen? I stuck a roll of cheap film in and voila, my pictures of the lawn the clouds and the house came out a lime green. I think there is something wrong with the shutter. It gets stuck in the open position.
