Help me Razor ID, please

Hello gentlemen,
I'm begging your help at identifying this razor that I recently bought:
Attachment 165773
Attachment 165774
Attachment 165775
On the tang it is stamped:
BEST QUAL
SILVER STEEL
GUARANTEED

and
MADE IN GERMANY

that's all. ???
It's full hollow, very thin blade, excellent manufacturing.

First of all it´s an nice blade.

This one is easy.
It´s made by C.FRIEDR. SCHMIDT. He Founded the company Revisor in 1919 and they are still existing today under new owners.
Historie
The Revisor blades are very good shavers.

Thanks, that' great news.
Then could it be possible to get a datation?

To get a date I think you should ask Thomas Kronenberg at Revisor.
He is also a member on the sight.
My own guess would be around 1930 - 1940.
