I'm trying to sort out the Dagors, and was wondering if anyone could point me to a specific, authoritative site that tells the differences. A lot of what I've found has been confusing, conflicting, and I'm sure sometimes wrong.
As an example, there are "Berlin Dagors" and Dagors marked "Goerz Berlin". There are also Golden, Gold-Rim, Gold-Band, and Gold-Dot Dagors. I think I'm sorting it out, but is there a reference article that has it right and all in one place? Thanks!
