Keystone camera questions

[Taylor Greathead]

Hi,

 

I'm trying to find out some technical info for the old Keystone 'A' series of 16mm cameras. I'm mostly trying to find out what kind of lenses I can use. I don't know the difference between the C-mount, S-mount, etc. Does anyone know what kind of lenses these take, or the lens size (ex: 28mm, etc.)

 

Thanks for any help or direction,

Specifically the A-12.

Ancient cameras with ancient lens mounts. Nothing has been made for them in at least 30 years.

Any "C" mount lens will do. They have a screw in base of about 25mm in diameter outside the threads.
