Paul Drees Razor

Hello.
As I said in the present yourself section, I´m a knife collector and now I´m starting a little collection of straight razors.
Few days ago I got a Dreifuss Paul Drees razor, Nº 39 6/8. It was very rusty but after a few hours of sanding, sharpening and adjusting, it came back to life.
I tried to find some information about this razor on line but didn't found much. If somebody can give me some information about this razor i will appreciate very much. perhaps how old is it?
Thank you in advance. Below a few pictures of the razor.
