Well, maybe it will cover 5x7 with minimal movements, stopped down to f/32.
In any case it will be a pretty lens, and useful - in a cheery, pictorial way - as a single cell
of 220 ish /f12.5 ish. Not soft, but even, smooth, but can't resolve pine needles at a quarter mile.
On a Crown Graphic, a pretty handy little outfit for the right photographer.
Ole is right, Voigtlander and Schneider made lenses on the Goerz principle but in a less efficient design. The results are the same, though (if a little less coverage). Great little lens.
