Boss, Solingen 9/16", do you have any info on this?

[kalleolle]

Does anyone have any information about this razor?

The text says "Boss"  and "B" on one side and "Solingen" and "B" on the other.
I have used it for a while in my honing practice, but now I have started to use it more and more in my "rotation".

On the internet I have found some info about a razor named "The Boss" by ERN, but I am not sure that they are made by the same manufacturer.

So my question is: do you know anything about this one?

Feel free to answer in German, I can understand when I read it, but it is difficult for me to write in german.
Danke
