All are in perfect optical condition. The eyepieces and erecting prism are marked C. P. Goerz Berlin. The telescope, mount, pier and eyepieces are all contained in a heavy duty wood plank storage case with iron handles and steel latches - a real treasure chest!

C. P. Goerz was founded in 1886 by Carl Paul Goerz. Originally, it made geometrical drawing instruments for schools. In 1889 Goerz began making optical lens under the name of Lynkeioskop C/2. Lens making became his primary business. In 1890, Goerz products were introduced to the U.S. during the World's Fair at Chicago. During the First World War, Goerz's main production was for the German and Austrian military. C P Goertz also made a series of telescopic sights for sporting rifles that saw some use during the shortage of military sniping rifles experienced during the early stages of the trench warfare that was to characterize much of World War I. Goerz was an early advocate for socioeconomic equality, and ensured that his employees worked no more than 48 hours per week and received generous paid vacation and holiday packages. Carl Goerz died in 1923. In 1926 the German branch of Goerz merged with ICA, Contessa-Nettel and Ernemann to form Zeiss Ikon.
This telescope is described in the Zeiss Ikon pamphlet, above-right, as a Goerz Schulfernrohr. The German word for telescope is "fernrohr" and "schul" means teach or instruct. So this can be described as an "Educational Telescope."
