Just about everything was a "Doppel Anastigmat", an "Astigmat", or an "Aplanat" in those days. Those terms weren't protected like the "proper" names (Tessar, Protar, Dynar and so on). One of my finest old lenses is an "O. Simon Dresden Weitwinkel Anastigmat No. 3".

A propos names: Many names were chosen to give the impression of being something they were not. The example in my collection is a Rodenstock Hemi-Anastigmat - nice lens, but absolutely not an anastigmat!

And BTW: My Serie III has an iris

Addendum: The Goerz Berlin lenses say "Serie III", not "Series III". Not to be confused with the infamous "Berlin Dagor".
