Older Scope

Does anyone on the forum have any knowledge of Hensoldt-Wetzlar scopes? I have one, a fixed 4x that I believe if from the 50s, at least the Brno it's on is. Any info about these scopes would be welcome. I would even be interested in having it refurbished if possible.
It is a Dural-Dailytan model. Thanks

Go to google , there is info there.

Thanks for the suggestion. Oddly enough, I already thought of that, and while there is lots of info, it's like most on the internet. Contadictory and not very specific.
