These binoculars were specially designed for the navy, they were extremely good binoculars for locating planes and ships.
This type of binoculars was mainly used for night time observations onboard U-Boats.
You could use the binoculars hand-held, or on a tripod, possibly with a headrest, on most original WW.2 images they were used without.
The prisms are huge in relation to the tubes and the rest of the binoculars.
The binoculars therefore give a humongous panoramic detailed widescreen.
The letter "T" on the left, "Transparenzbelag", indicates that the lenses are coated with an anti-reflective coating
that improves the light transmission in the lenses by 80%.
