I just made a deal with my Mom. She got one of my almost new Weishis in exchange for this beauty. The razor has been in our family long before I was born. I remember my Dad using it when I was a child. When Dad discovered cartridge razors, it was handed "down" to Mom. Unbeknown to me she still used it until last week. Under the head one can read (with magnifiers) "Made in Germany" and "D.R.P.". My interpretation: "Deutsches Reichs Patent" (Patent of the German Empire), which suggests it was made before 1945. With its 45 degree angle it is the slantest Slant I've ever seen! No, I'm not brave enough to use it.
