New Old Blades

I bought 3 razors the other day from and a local antique store, I am trying find a little out about one in particular. I have not been able to find anything like it online yet. One was a Torrey, completely intact with what appears to be an aluminum hanlde. Another is the blade of a Keen Kutter with quite a bit a rust, with I hoping to use as my first restoration. The last is the one I am curious about, it is very rusted, but the manufacturer is T. Mansour & Son of New York on the shank, and the other side seem to have Germany on it but I can't make the rest out, the blade has 3 faces on it, the German Emperor, the Austrian Emperor, and I can't make out the other. I did a little research and it looks like Richard Korkemas operated under T. Mansour & Son. Does anyone know a little more about this razor?
