could someone teach me some history?

[Ross31]

I have some pics of my grandfathers straight razor and was wondering if someone could shed some light on it's history if there is any. The part between the blade and the thumb rest read "56 Fredrich Ern"
TEVA (I think, cant really make it out with the oxidation/rust that needs removing) and Solingen Wald. Don't really care how much it's worth or anything like that, just wondering if it was something he got here or maybe in Germany when he was there during the 'ol WWII, and if there is any history behind the particular model or anything of that nature. I'd ask him, but as with so many things, he's made the move to the place of the perma-perfect shave (and halos and wings) hahaha.

thanks,

Ross
