A Google search showed Vitry Freres as being founded in 1961 according to a company profile on bloomberg.com however there is a company named Vitry in Paris that claims to be in operation since 1795 they are both cosmetic and personal care companies. Most likely that razor was a contract razor. No clue who it was made by if this is correct.
I would think if the scales are.steel they would show rust since.the.blade shows a little. They could possibly be pewter.
