Or a Dogmar

If it's a Dagor it'll be marked as Dagor, or Double Anastigmatic Goerz in English or German depending on where it was made. There are unnamed Goerz lenses on some of the German company's plate & roll film cameras, these would have been the budget versions, the Dogmar and Dagor were used on the top of the range cameras.

Most LF lenses aren't designed for use at full aperture, Tessar's & Tessar types are soft at the edges & corners until stopped down to f16/f22.
