U.D.F - 7 X 50 U - BOAT CONNING TOWER BINOCULARS- CARL ZEISS CA. 1943

These binoculars were used on German U-boats.
They were mounted on a permanently present metal stand at the front in the conning tower.
The UDF 7x50 binoculars were a part of the U.Z.O (Uberwasser – Ziel – Optik, or: U-boat aiming optics).
The binoculars were deployed during the lancing of torpedoes on the surface.
Because of its special build and use of materials this viewer is pressure- and watertight up to 30 atm / 300 meters.
Despite the fact that the viewer was watertight it would only be mounted after coming to the surface,
and afterwards it was taken back inside.
In the case of a sudden emergency dive the viewer could be left behind on the conning tower.
These binoculars have a fixed focus.
Executed with a knob on the right eyepiece for: Hell & Dunkel (light and dark).
At night the knob would be put in the Dunkel position, the vertical line graticule in the right eyepiece
would then be illuminated through the use of luminous paint.
At the back there is a bending bar for adjusting the eye position.
It has retractable rubber eye caps with side shield against light shining in from the sides,
and it is equipped with little holes against condensation.
Pure untouched and unrestored!
Condition:
The viewer has the characteristic signs of wear, these are where they should also be.
The viewer was clamped on UZO, a metal column on the bridge, at this spot there always appeared small traces of wear.
The binoculars were used in all-weather circumstances, the instrument therefore has a beautiful patina.
The optical part is good and clear, the lenses have no scratches or chips.
The horizontal bending bar for the eye distance is in good working order.
These binoculars come with foldable rubber eyecups on hinges, quality of the rubber is good and still soft.
Both hinged eyecups lift well and operate smoothly, clicking down into place.
