I just got a 10-3/4" labelled Gennart f/6.8 which I am comparing side by side to a Goerz 12" Dagor f/6.8. The reflections(one bright, one dim) are identical. Unscrewing the elements, the elements of both lenses exhibit the same convex/concave - concave/convex relationship leading me to suspect that the Gennart is also a double anastigmat "dagor" design. So far, I haven't found anything on the web about Gennart lenses, but there is some info on Gennart cameras. Can anyone out there tell me if Gennart in fact marketed a double anastigmat "dagor" lens and if possible, what company produced them for Gennart? Both the 12" dagor and the 10-3/4" appear to be in the same size(externally) compound shutter although the 10-3/4" lens is a slightly smaller piece of glass.
Thanks!
