Identity of the manufacture.

I recieved this from Dr. Hans Seeger , international optics expert.

"bef is the code for
Riefler, Clemens, Fabrik mathematischer Instrumente, Nesselwang/Bayern" .

Goes to show that not all lists are complete and sharing information is the key to knowledge and understanding.
Thank you Hans.
