Cp Goerz Berlin Serial Numbers
In 1895 Goerz founded a branch in New York that started its own production in 1902 and was to become the C. Goerz American Optical Co. In 1905 (see here for dating these serial numbers). This company continued to operate independently in the US until 1972. Until WWI many great companies cooperated with Goerz. Mar 29, 2016 - WW1 Binoculars C.P. Goerz Berlin Trieder Binocle Pagor. If the serial numbers and chronology match, the glasses should date from the early.
I'm a large format b&w photographer with a great interest in classic lenses, of which I have a number, in addition to some modern lenses. My first, and one of my oldest, lenses, is a CP Goerz Berlin Series III f/6.8, 8 inch 'Goerz Double Anastigmatic' (Dagor) in a compound shutter (which believe it or not works well!) From reading Kingslake and Vade Mecum, I know that because it says 'Goerz Double Anastigmatic' instead of 'Dagor', it is prior to 1904, when they began to use the name 'Dagor' (apparently to differentiate themselves from the other double anastigmatics.) But as a matter of pure curiosity, I'd love to know the exact year. The serial number is 140390. Does anyone know of a site or other source which provides a cross reference between Goerz/Dagor serial numbers and year of manufacture? Right now I know that it is between 1892 and 1904. Thanks, Paul.
The lens was finally completed on September 23rd at 3.47pm 1903. The final optical bench test was given by Otto Plankshaft who deemed it above average and gave it his stamp before it was sent to the shipping department. Otto had just been given the news that he was the proud father of twins and he was allowed to leave work early. Some anecdotal evidence does mention that Emil von Hoegh slapped him on the back and called him the true 'double' anastigmat and his nickname from that day was 'doppeldaddy'. The lens was then sent via steamer to New York where it was coupled up to a shutter about thirty years later. The lens has seen action in both world wars and was used as both a portrait lens and as a landscape lens used for battlefront recon. A shellburst close by did some damage(during WW1) to the front ring that was replaced at the factory free of charge since the owner in the US was an expat with some connections in the food distribution services for the British troops.

My records after 1950 are a bit sketchy but I hope that helps! Netshade for mac.
