7 x 50 Nedinsco Venlo - Nedelta 1955
The binocular was produced for Dutch army, by Nedinsco in Venlo Nederland. The short history of the Nedinsco factory you can read in the article “Gas Mask” - Unusual site page 8.
Nedinsco it is an abbreviation formed from - NEDERLANDSE INSTRUMENT COMPAGNIE.
After the WWII the factory was bought by Dutch industrialist - Gerard Beusker and the optical production was renewed. In 1953 the company became independent.
In 1950s the Company, among other items, was produced:
- 7 x 50 Nedelta binocular
- Telescopes.
The Nedinsco Nedelta binocular is based on the Zeiss 7 x50 model Binoctar. We made a test and it is the same angle of view as 7 x 50 Binoctem & Binoctar - 7,3 degree.
1. External Features
The binocular body is made of aluminium alloy with green vulcanite covering. Other parts are made from very thick metal, including the objectives rings . Presumably, it gives weight to the binocular.
The binocular was produced in black and gray color, as well.
The eyecups are made of a hard plastic material. It has a ridge on the top for the filter to clip on.
As it is a military binocular each each eyepiece can be focused independently from -5 to +5 diopter.
Below of the diopter ring is a large returning ring.
On the left plate there are engraved letters - M. v. O. (Ministerie van Oorlog) - Ministry of War and production number 3561 N. (Pict 2)
In 1959 the name of the Ministry was changed into M. v. D. (Ministerie van Defencie) - Ministry of Defense.
On the right plate is engraved (Pict 3); the Nedinsco logo, designed after the war, the binocular name - Nedelta and magnification.
On both plates are mounted red air drying ports.

The construction is similar to the Carl Zeiss Jena 7x50 Binoctar early model. There are added two fastening screws into the upper cover plates. The prisms have two groves (slots), which when it is mounted in the body, there is two small punch marks made on the metal prism seat (look at the above picture). The punch marks are locating into the slots of the prisms to stop movement of the prisms.
This kind of mount was used in WWII time on Zeiss 7x50 models.
In the left ocular is fitted a horizontal reticule with scale to 5 each side.
