Need Help 2 unknown vintage OC





What kind of brand is that? 

I have two almost identical vintage safety razors here. 

I got the left one a few years ago and it was in a box from the Wuttig Apperatebau company. It is chrome-plated and weighs 78 grams an No aritations.

I got the right safety razor today, it is almost identical. It's silver-plated! and has two aritations at the end of the handle. A ball and a hollow. 

It weighs 78.4 grams and you cannot remove the sleeve from either razor. As with the old Rotbart 15 safety razors, they are fastened with a sleeve. 

Both have 12 teeth and a bulldog handle and are of very high quality. Who can tell me more about this safety razor? Manufacturer??
