my dad has his fathers safety razor from back in the day i know its brass it has a nice patina on it, and i can see no names anywhere there are some faint numbers stamp into it ill see if i can read em and ill get a pic when i can.

it is a concave 3 piece design the handle screws into the blade holder. im guessing its pre 1940's his father was killed in action so its at least that old.
