Dovo Facharbeit

[Bezgo]

Hello, i have recently purchased 2 straight razors, one of them is the Dovo Facharbeit and I've had a hard time finding much of anything on it. I was wondering if ou guys might be able to tell me a little bit mroe about what exactly I have.
That being said they are my first straight razors and Ilook forward to shaving with them once I get them to shave ready condition. (the other razor is not with me or id include pictures and info about it as well, so that will be another post once i have it ready).
