Collecting Military Binoculars
German Binocular 6 x 36 "Jagd Dialyt Wacht" Hensoldt Wetzlar 1915
In 1849 Moritz Carl Hensoldt (b. 1821 - d. 1903) and his brother-in-law Carl Kellner (known best for his eyepiece design) began a business for the fabrication of telescopes. By 1850 Hensoldt formed his own company "M. Hensoldt & Soehne AG" for the manufacture of optical instruments. By 1928, the Hensoldt company with its factory in Wetzlar had the Carl Zeiss company as a shareholder. Zeiss thereby acquired a partnership with a manufacturer best known for their roof prism binoculars introduced in 1897, and in 1905 the "Dialyt" series of Abbe-Koenig in line prism binoculars, and rifle scopes. Hence the similarity between the appearance of traditional Hensoldt roof prism binoculars made since about 1905 and several Carl Zeiss roof prism products up to today.
This roofprism bino is still in a good condition, some loss of paint, but the optics are clear and undamaged. The central focus works ok.
