Help identifying this Bismarck razor.

[Blademen]

First of all I want to say thanks for all the help I received from all the members. I had so many questions and everything is finally coming along. I’m getting good shaves, my stropping technique, and honing is getting better thanks to all the information you guys gave me. Special thanks goes to Glen, Lynn, MileMarker60 and Wid. You guys help and taught me so much.

I pick this razor up today and was wondering if anybody could helpidentifying it. It’s a Bismarck and marked on the other side Jos. Erh. Schulte Siedlinghausen 1/westf. This is the puzzling part the scales are signed what appears to be Ylorsim.

I’m sorry for the quality of the photos.

Best regards,
Blademen
