Thread: Not a roxo, but what is it?

Hello, I have recently begun trying to learn how to hone my kitchen knives, I saw someone, on youtube, honing a regular knife and then shaving with it. This got me interested in straight razor shaving, and the history and different varieties of straight razors, and the maintenance and honing of these instruments. I asked around, and my mother-in-law thought that there might be something in an old cottage her mother had inherited. And sure enough, in a drawer I found this: hmm, I don't know how to put pics in between text blocks so they're at the bottom.
Anyway, the case says: Marsh Brothers & co, Ltd Sheffield, England. Special roxo razor.
And on the razor: Richard extra 3, and on the other side: Alfred Johnson Stockholm, and on the tang: IMPORT. The man who owned the razor lived between 1890-1967. The handle seems to be made of some plastic stuff.

Unfortunately there is a big nick on it...

Questions: If anybody knows anything about this razor, I'd be grateful.
Is it possible to restore it to shave ready state? Is it very valuable or can I use it to practice my honing skills? I also found some sharpening/honing stones, questions and pics on those later.

Best regards
Leif
