The Viewfinder is particularly bad on this camera. The patterning shown is the worst case I have seen of the failure the seal between the tube and the bonded (or perhaps not bonded) flat glass faceplate.

Many otherwise good viewfinder tubes, from that period suffer a similar fate. It is hard to do much about it. Later tubes from the same manufacturer do not have the problem.
