Goerz Roberstson 12'' ?

[Waldo]

Does anyone have any information on this lens? I cant find a thing.

Robertson made graphic arts cameras, the huge kind that were built through a wall with the groundglass side in the darkroom. Goerz supplied "OEM" lenses to them. I used one of those beasts at a job many years ago- it had a 19" Goerz-Robertson lens. Your lens is almost certainly an Artar with another nameplate.

Thank you very much. Now I'm finding a lot of information on the lens. Still nothing on the Goerz Robertson one though.


Edit: Nevermind, Im very tired. I for some reason didn't get what was being said.

So you think that my lens was used in one of these monster cameras?

It's most likely that your lens was made by Goerz American Optical Co., for Robertson, as original equipment on one of their graphic-arts cameras. It's equally likely that your lens is an Artar design, which was the industry-standard lens for close-up and copy work.
So look up "Goerz Artar" or "Red Dot Artar" and you should find the information you're looking for.
