All the Zeiss lens serial number charts I have found seem to start in 1912 with SN 137,418...
However Zeiss began making camera lenses in 1896 (according to Zeiss website) so we are missing over a decade of SN data...
Here is Tessar 70,610 on a very early compound shutter...
The compound shutter began in 1904 and only had this silver design for a few years before going all black.
As I can't know if the lens originated in the shutter how can i best date these pre 1912 lenses?
