Petri Computor II

This is a later deriviative of the Petri computor 35, featuring a fast 1.7 lens and coupled rangefinder. The camera appears to calculate shutter and aperture automatically, despite a confusing F-stop indicator on the lens barrel, which seems to be just for the benefit of flash photography, so does not actually control the aperture. The bright finder is not so very bright on this one, although it may have yellowed with age.
