An early (4 digit serial number) Imarect finder in excellent+ cosmestic condition. Functions fine, but with one issue described below. The Imarect is a cropping, shoe mounted, prism finder with settings from 35mm to 135mm. It provides manual parallax adjustment via a small thumbwheel at the base. Mechanically everything seems fine. There is some minor brassing on the eyepiece but no rust.
However, there is a spot (fungus?) on one of the inner elements. This spot is a small black dot surrounded by a grey "halo". The black dot is about 1/3 the total size. It disappears at the 85mm setting (because it's a cropping finder). It doesn't prevent use of the finder at wider settings, but is distracting. It's very near the bottom at about the "5 o'clock" position. As to size, I estimate that the entire spot is about 1/10th the total vertical dimension at the 35mm setting. Other than the spot, the finder is clear.
There is a discussion about opening and cleaning here:
