Hensoldt Prototype
The history of this binocular, as a part of our collection is unusual. Many years ago, we have been in Warsaw. There is an antique market on every Sunday. Walking among tables, we looked in a box with some rusted metals. Among them was unusual shape like a big ‘U’ for an experienced eye it was a binocular, but for that salesman it was a piece of slightly rusted metal.
At the annual meeting of Binoculars Historical Society, in Wetzlar, we have met some specialists from this model. In their opinion it is a prototype Hensoldt produced about 1902 -1904 in Wetzlar.
The binocular does not have a production number, a name and any other markings on the body. Presumably, the magnification is x6. The diameter of the objective is 26 mm.
As we can learn from new book “Zeiss-Feldstecher Handferngläser von 1894 – 1919 Modelle – Merkmale – Mythos” by Dr. Hans T. Seeger, at that time the factory Hensoldt was produced many binoculars with similar magnification.
It is rather weighty binocular for that size. The weight of the binocular is 628 gram.
As Dr Hans Seeger says, the body is an aluminium alloy. The alum alloys was in use as early as before 1900. So it is very unlikely that the body is pure aluminium.
Some parts of the body, such as object glass metal work, the central hinge unite and eye piece tubes are made of brass.
We can assume, that this specific body shape of the binocular was designed for a new kind of the prism which is fitted in the binocular; Sprenger – Leman. The construction of the Sprenger – Leman you can see on pdf:

Carl Zeiss Monocular 8 x 30 B - ca 1964-1966
The Porro prism monocular 8 x 30 B, produced by Carl Zeiss, is a telephoto attachment. It can be used as a hand-held as well. The focusing adjustment is located on the front objective ring. The scale of focusing is given in feet and meters. The focus is very close to about 2-3 foot (60-90 cm) to infinity.
It is possible to use the monocular as a telephoto lens, without an adapter, but only to one photo-camera - Contaflex Super. Using other cameras the adapter is required.
The lenses are fully coated. The kind of coating suggests it is a later production of this model.
As a telephoto lens at full zoom the lens equivalent is more than 400 mm. The wildlife, nature enthusiasts photographers highly valuated the monocular.
On the cover of the leather case is embossed Zeiss Ikon logo. It suppose the monocular was used as a camera accessory.
The next generation of 8 x 30 B from 1969, is no longer Porro prism, it is Dialyt prism.
Production number - 646303.
