Hensoldt Wetzlar microscope serial numbers

[Yuval Goren]

Hello all,
In my collection of field microscopes, I hold a nice series of pre- and post-WWII Hensoldt "tashenmikroskopes", including the different models of Tami, Metami and Protami. They all bear serial numbers, but as much as I was looking for a date list for the Hensoldt products according to their serial numbers, I was insuccessful. I even wrote to Hensoldt-Zeiss about it but got no answer. Could anybody help me by directing me to such a list, or by copying one here?
Thank you,
Yuval
