Hi, I went to a Collectables fair today here in Melbourne and ended up buying a straight razor for my son for Christmas. It looks as though it has a bakelite handle with either end capped off with either silver or steel. On one side of the handle it says, BISMARCK SOLINGEN. On one side of the blade it say, Krosskeys and on the other it says, J.NOWILL & SONS then SHEFFIELD and it has 2xkeys crossed and EST written under them. On the blade it says _______ MADE AND GROUND, the first word is hard to read.

I am hoping that someone can help me date it?

Thanks everyone!
