Another big lens finally cleaned up a mite. Yes, I've done the Googling, but there is nothing on this one.

Markings, top-down

7.
Portrait Euryscop
No. 33###
Voigtlander and Sohn,
Braunschweig.

I've found 5's, etc, but not the 7 model. The "c" in Braunschweig is perfectly malformed so that it is an "o", a clear error.

Info?

Oh - picts. Forgive quality. It's been a dark and rainey day.
Other camera is for scale. Please see both.
