At the dawn of the 20th century there was enormous development and innovation in the area of binoculars for military use.
In 1917 Krauss put the Longue Vue Monoculaire into the market under the name M.1917, enlargement 15 x 23 x and 30 x 80.
In 1816 Busch, Rathenow also introduced into the market similar binoculars with
rotatable eyepiece, enlargement 12 x and 20 x 80.

This type of binoculars originated during the 1st World War.
In 1910 Zeiss was the first to put on the market the Starmore, a telescope consisting of a solitary tube with rotatable eyepiece for varying strength set-ups.
The Starmore later evolved into the Starmorbi, an enormous commercial success.
The Starmorbi as well as the Krauss M.1917 are still on the website as reference to look at (sold).

Later Zeiss further developed its models and the Zeiss Asembi was introduced around 1914.
In the Astro catalog Nr 94, 1936 these viewers were lauded for their astronomical characteristics for looking at the stars.
Using an enlargement of 40x the rings of Saturn then were spectacularly and beautifully discernable.
After the Asembi the development and the quest for further optical perfection went on, the model on display here is an example of this.
* The model now additionally has been fitted with a nonius of - 20º + 0 to 80º.
* Improved and refined optics because of lens coating and extra transparent T coating.
* The object lens is enlarged from 60 mm to 80mm!
* Slid sun shields (in the version that was built last the object lenses were placed back 8 cm inside the tube).
This model was produced around 1939/1940.
Zeiss started its blc code around 1940, that is also approximately the production date of these binoculars.
