In the Federative Republic of Brazil armed forces, military service binoculars were marked to identify them as government military property.

 

Military service binoculars were issued to soldiers with specialized functions. For example, group leaders and artillery observers were issued military service binoculars to perform their duties.

 

The most common type of service glass used by the armed forces of the Federative Republic of Brazil during the Second World War was the 8×30, based on the 8×30 Carl Zeiss Deltrentis, that first appeared in 1920.

The body was made of magnesium and was featherlight at just 390 grams. The wideangle eyepieces, designed by Albert Koenig, were free of distortion and contained 4 lens-elements. A single layer anti-reflection coating with a bluish color was first added during the Second World War. Production of the 8×30 Carl Zeiss Deltrentis was eventualy halted around 1995. 

 

The number “8” identifies the magnification power (in this case, “8” indicates that objects appear eight times closer than their actual distance).

 

The number “30” identifies the diameter in millimeters of the front (objective) lenses — the light gathering lenses — in this case 30 millimeters in diameter.


Vulkanite” schwarzes Kunstleder (black synthetic leather) Körperbedeckung (body covering)

Dienstglas Leather or "Vulkanite" body coveringIn Germany in the 1930s, an early type of black plastic synthetic leather called “Vulkanite” was used as the body covering of military and commercial  Dienstgläser (service glasses) manufactured before World War II.

This “Vulkaniteschwarzes Kunstleder (black synthetic leather) Körperbedeckung (body covering) was the most common Dienstglas body covering used by the German armed forces (and also by most of the other armed forces of Europe) during the early years of the Second World War.

TM 30-506, WAR DEPARTMENT TECHNICAL MANUAL, GERMAN-ENGLISH MILITARY DICTIONARY, WAR DEPARTMENT, 20 MAY I944

The TM 30-506 manual describes “Vulkaniteschwarzes Kunstleder (black synthetic leather) Körperbedeckung (body covering) as “Kunstleder n” artificial leather.



Schwarz „Reis“ Raulack (black “rice” rough lacquer) Körperbedeckung (body covering)

Dienstglas "Rice"body coveringEarly in the Second World War, a black Rauhlack (rough lacquer) body covering called schwarz „Reis“ Körperbedeckung (black “rice” body covering) also became a common Dienstglas body finish.

This new Dienstglas body covering began to replace the black “Vulkanite” (synthetic, leather-like, early plastic) body covering material on the housings of German field glasses.

The particular consistency of this schwarz „Reis“ (black “rice”) Rauhlack (rough lacquer) Körperbedeckung (body covering) was achieved by mixing crushed rice or finely granulated cork meal with black lacquer paint.

This schwarz „Reis“ Rauhlack Körperbedeckung (black “rice” rough lacquer body covering) became the most common Dienstglas body covering as the war progressed through 1942 and 1943.

The Ministry of War (Ministério da Guerra) was a historical government ministry in Brazil that was established on April 22, 1821. It served as the primary civilian authority for the Brazilian Army until it was renamed the Ministry of the Army (Ministério do Exército) during the 1964-1985 military dictatorship.

The Ministry of the Army was later merged as the Army Command (Comando do Exército) into the unified Ministry of Defense (Ministério da Defesa) on June 9, 1999. Today, the Army Command, headquartered in Brasília, operates under the Ministry of Defense.

Brazil’s most recent military dictatorship lasted 21 years, from the 1964 coup that ousted President João Goulart until the transition to civilian rule in 1985. This period was characterized by severe political repression, including the systematic use of torture, censorship, and the disappearance of hundreds of opponents, with the Truth Commission later documenting 434 deaths and missing persons.

The regime’s legacy remains a contentious political issue in contemporary Brazil. While former President Jair Bolsonaro expressed nostalgia for the dictatorship and praised its officials, current President Luiz Inácio Lula da Silva has emphasized the importance of defending democracy and remembering the era’s human rights abuses, noting that the military’s institutional autonomy was preserved during the 1985 transition, allowing it to maintain significant influence in Brazilian politics today.

The Treaty of Versailles was a peace treaty signed on June 28, 1919 that ended the war between Germany and most of the Allied Powers. It was signed in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war.

The treaty required Germany to disarm, make territorial concessions, extradite alleged war criminals, agree to Kaiser Wilhelm being put on trial, recognise the independence of states whose territory had previously been part of the German Empire, and pay reparations to the Entente powers.

Military Restrictions

The treaty was comprehensive and complex in the restrictions imposed upon the post-war German armed forces, the Reichswehr. The provisions were intended to make the Reichswehr incapable of offensive action and to encourage international disarmament.

German officials conspired systematically to evade the clauses of the treaty, by failing to meet disarmament deadlines, refusing Allied officials access to military facilities, and maintaining and hiding weapons production.

The Treaty of Versailles prohibited German companies from producing war materials. The treaty did not ban German companies from producing war materials outside of Germany, so companies moved, or opened new companies, in the Netherlands, Switzerland, and Sweden. In 1921, German troops were sent to Sweden to test weapons.

The Treaty of Versailles forced Carl Zeiss to relocate a significant portion of its military production to the Netherlands and Sweden. This influx of equipment and expertise brought new technologies and innovations to the country, influencing the development of Nedinsco.

The 1919 Treaty of Versailles that ended the First World War forced Carl Zeiss Jena to significantly reduce its military production in Germany. To circumvent this restriction, thousands of boxes of equipment and storage were illegally transported from Germany to the Netherlands and Sweden in 1919 and 1920.

In early 1921, the German optical manufacturing firm, Carl Zeiss of Jena, Thuringia, Germany, created a new company, Nedinsco (Nederlandse Instrumenten Compagnie), to produce cameras, binoculars, rangefinders, microscopes, periscopes, and similar optical instruments in the Netherlands.

Initially, the Netherlands Instruments Company (Nedinsco) set up its headquarters in an old disused chocolate factory in Flushing, Netherlands. Two years later, the company moved to a new location in Venlo, Netherlands, and constructed a new factory.

The architect, Hans Schlag, was commissioned for the design of the new Nedinsco factory. He and his design team built a special tower that was used to align optical instruments and to calibrate the larger measuring distances. This was done by adjusting the instruments to the many church towers in Venlo.

The tower, built in the Bauhaus style, is a beautiful national historical monument in the heart of Venlo.

As a subsidiary of Carl Zeiss Jena, Nedinsco inherited the German firm’s expertise in optical technology. This allowed Nedinsco to produce high-quality military optical equipment, including military service binoculars, telescopes, and other precision instruments.

Nedinsco’s early production focused on military optics, with exports to countries such as Switzerland and Sweden. The company’s products were well respected for their exceptional quality, and the company quickly gained a reputation as a reliable supplier of optical equipment.

Nedinsco’s was a well known subsidiary of Carl Zeiss Jena, located in Venlo, Netherlands, producing high-quality military optical equipment for export.

In the 1930s, Nedinsco grew into a strong economic company with a beneficial effect on the regional Dutch economy. During the Second World War, Nedinsco manufactured optical equipment for the German war effort.

In 1944 , an aircraft bomb, intended for the nearby city bridge over the Maas River, destroyed the factory building. Only the tower survived the bombardment.

After the war, Nedinsco was confiscated by the Dutch government and, after a period of temporary management, was sold to the Arnhem entrepreneur G. Beusker, who rebuilt the factory. In 1953, it became an independent company.

Today, Nedinsco is a supplier of systems and modules for the semiconductor industry. The company manufactures diagnostic systems, and products for the defense industry. Nedinsco is a leader in the manufacture of optical, mechanical, and electronic technologies for safety and security.
