Can someone ID this brass Voigtlander & Sohn. Serial 22089 ?

Joseph, here is the thread i referred to above:

If you look at later posts, you'll see that about 5 C "euryscopes" had been identified on this forum. I recollect seeing a half dozen or so sales of these on eb@y in the past 5 or so years. So, not too common, but not too uncommon either. Definitely a nice lens.

I have updated the list of known proto- euryskops.
This last one appears to be a series IV size 4 type.
I include the table for this series below.

There are three outstanding problems with the C version:

Are the two cells identical?

Are all C models an early series IV?

Are they, perhaps, the same size?

Hi Steven,

From samples i've seen, the C lens has symmetrical cells, 60mm dia. Little bit shorter focal length than a bona fide euryscope IV #5, and operating at f7.
