Im a large format bw 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 f6.8, 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, Id love to know the exact year.

Does anyone know of a site or other source which provides a cross reference between GoerzDagor serial numbers and year of manufacture Right now I know that it is between 1892 and 1904.

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.

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.
