Universal viewfinder correct image (Imarect)

Every screw mount Leica’s is equipped with a finder that displays the image of a 5 cm lens. For all other focal lengths a separate finder had to be used. Leitz made many finders for specific focal lengths, but also a number of universal finders. This type that has been produced between 1939 and 1963 has a double prism mechanism, which gives it the correct image. This type has settings for 3,5, 5, 7,3 (or 8,5 cm), 9, 10,5 (only on early models and 13,5 cm.

The finder has a parallax correction mechanism in that the viewer tumbles a bit for shorter focus distances.  Therefor this viewfinder is also useful for 5 cm lenses.
