8 x 30 Nedinsco 1934
The 8 x 30 Nedinsco is made in January 1934 for the Swiss Army.
The collectors sometimes refer as it is a gas mask model. After a dissembled of the binocular it is visible that it has a Deltrintem or Deltrentis type of eyepiece. It is not a symmetrical eyepiece construction.
The eye relief is only 10 mm with extended eyecups.
The diameter of the aperture ocular lenses is 19 mm (measurement was taken with vernier caliper). The complete lens would be slightly bigger diameter to allow for the retaining ring.
The binocular have a very informative description on both plates.
On the left plate is engraved:
- the Swiss cross;
- production year 1934
- Nedinsco logo.
On the right plate:
- Swiss cross;
- “Armee Modell”;
- Swiss Army Number: 3484
The Swiss Army number is repeated on the bottom right plate. The Swiss cross is engraved on the bottom plates as well. Unfortunately, the description is nearly invisible, because the previous owner removed the paint from all plates.
The binocular is fitted with a graticule, but in unusual way, it is fixed into the left ocular.
The binocular measurements are; Weight 666 gram; High 105 mm;
The prism house is built from aluminum; hinge, oculars and objectives rings are made from brass. The body is covering with vulcanite material.
The production number is inserted on the edge side of the right top plate facing the top bending bar – No. 1624068

The binocular is built up from alloy and covered with black gritty textured paint. The body is fitted with desiccator cartridges at the bottom of prism house.
This model is not very common. It has very stiff focusing on the eyepieces. So the eyepiece focus does not move accidentally.
The eye lenses are made from soft glass and often scratch and can split in the half. The eye lenses are unique to this model. Any other eye lenses will not fit (!).
The prisms are Porro I system. The optics is fully coated.
This binocular should have the special Bakelite rain cover “Benutzer”, that can be fitted on the mounting adapter on the upper hinge.
The binocular is with a special high quality leather case. It has fitted with the circular wooden blocks, on the base of the case. The shape of them are the same as the eyecups. On the top inside lid is a pocket probably for cleaning clothe or brush.
 
The case has embodied letters J.F. and swastika with the military test stamp - WaA C52. The production year is embodied as well - 1942. The letter - J.F. are showed in the war time code book, but without any makers name.
