Check here at: www.rapidotechnology.com, I do have some C-mount solutions, for example, adapter for the Kinoscope anamorphic lens, and adapter for Yashica anamorphic lens. Those anamorphic lenses are developed for 8mm camera & projector, you can used the lens on both camera and projector. I recent found a CANON C-8 scope lens, seems it was also developed for 8mm camera/projection market. :-)
