Konica  Koni-Omega Press Camera with Hexanon 90mm f3.5 Koni-Omega NO.3700797 Lens.  Made in Japan. 

All the buttons and dials appear to work, however, I can not confirm it.  The camera needs cleaning.  It is being sold AS IS.

Built in the late 1960s. The standard lens is a very sharp 90mm F3.5 Hexanon made by Konica.  The camera uses a push-pull lever to advance the film and cock the lens shutter. The camera is heavy and solidly built and would make a fine introduction to medium format for anyone interested in exploring.
