Here is the nice right angle viewfinder for Hasselblad 500 series cameras. It provides a crisp image that is about 2.5x magnification of the image on the ground glass that makes framing and finding critical focus much easier and more accurate.
It is in great condition with moderate cosmetic wear and works perfectly. The glass and prism are clean and scratch free with no haze or fungus. Mirror has small amount of degradation but this won't affect your image. The mount is in excellent condition and interfaces with the camera securely.
This is a nice one.
