Hello! I've had this knocking around my drawers for a while and was wondering if anyone had info about it! Thanks!

Heavy, with f stops from f/6.8-45, and no other information except what you see on the lens. The rear element has a matching serial but I can't seem to unscrew it so I don't know why they would stamp it twice. Just curious about the lens.
One would expect it to ne a Dagor or a Dogmar (Dialyte) but it's very late Goerz production. Maybe an enlarger lens or possibly maccro lens, biut with no FL marked it may have neen a special order.

I picked up one of these for free. See the following link:

It's probably a factory coated Dagor. (From the serial number, and since it appears to be coated in the photo.) To determine focal length, use the lens to focus a distant light bulb onto a piece of paper. The distance of the paper from the lens when in focus, will give you an idea of the focal length. Mine was 210mm (8 1/4").

The K in the serial number is for Kenro.
Goerz traditionally had serial numbers on both lens cells. A single series III/Dagor cell could also be used as longer optic.

Hi Guys,
Koh303 let me know it is off a Kenro repro camera. If it's of any value to anyone, send me a PM I'll mail it to you
