Is it a Contaflex? I had one of those with a 45mm f/2.8 Pantar lens, selenium light meter coupled to the f/stop and shutter speed RINGS, which were located concentric with the lens, a la the old Hasselblad style...it has a weird ultra-clear viewfinder screen in it, VERY bright, with NO FOCUSING possible on the outer parts of the viewfinder's ultra-clear image. The focusing was a small maybe 4mm diameter split image rangefinder and narrow 8mm microprism doughnut. It was for all intents and purposed, kind of a "point and shoot" 35mm SLR made in the late 1950's/early 1960's.
Can you snap a pic and post it, so we van ID the camera?
