Below is my most current information relating to Voigtlander serial number dating. However, as more and more contemporary sources are located it has become apparent that many published and on-line listings are not entirely accurate. Part of the serial number sequence of lenses made by Voigtländer There is a case which once was beautiful but is now a bit poorly. There is a magnification mark on one eyepiece which reads 0X I presume this to be 10X and the 1 has worn off. There does not seem to be much online that goes back so far. I have acquired this pair of very old 'late 1800s' I think, and would like some information.
I appreciate that this is my first post on this forum but I am desperate for help and I know there are vintage binocular experts on here.
