Zeiss Ikon Icarex 35 CS.
The shutter fires and the camera looks quite clean and functional.
The prism can be removed and houses the meter. I have not tested the meter a I do not have the right battery. I do not think it will work as the top dials appear to be seized.
This version has a Bayonet Mount Lens. F2.8 50mm Carl Zeiss.
