In this posting, I’ve put some data tables for help when using the fully manual Argus C3.

This is a clockwork self timer, that came in a blue Bakelite case with instructions. Another useful addition from ebay.

This is a conversion of a product that I’m pretty sure was originally supplied with a PC type connector. However, functions well with the C3 plugs, and saves me lugging the huge Argus originals. The reflector dish completely retracts, making it very portable. It also has the benefit of tilting, allowing bounce flash.

These are the original lenses as far as I know that Argus released for the C3 range of cameras by Sandmar, there’s a Wide Angle and TelePhoto.
There are 2 of them, each in a leather case with blue velvet interior. Both in near mint condition, and no marks on the glass that I can see [...]

I currently have 3 C3’s, 2 originals, no accessory shoe, with flash mount holes. These were in production between 1939 and 1957, and came with a 50mm lens capable of aperture to f/3.5.
