This camera has a Zeiss Tessar series Ic 10cm f3.5 lens, and it has two aperature scales. In addition to the usual f stop scale, it also has a scale marked "mm", which evidently tells the aperature diameter in mm. This scale is tick marked for every mm, and numerically marked for 17, 12, 8, 6, 4, and 3mm. These numerical markings do not line up when the marked f stops are indexed; they seem unrelated. I've never heard of such a scale, and cannot really imagine how it would be useful.
