I just bought a blade and am looking for information on the manufacture. The manufacture is D.J Faour & Bros. I have done as much research as I could and came across some information.

They were some sort of Bankers in 1901
In 1903 a band of safe crackers with "skill" tried to break into their safe but failed and was only able to steal $10

In 1926 they became an official business and obtained capital from the bank of Brooklyn brothers are named George Joseh Faour and Dominiek Joseph Faour and at this time applied to be named DJ Faour Brothers

In 1933 they seemed to have gone Bankrupt and their affairs were liquidated.

My problem I can find nothing about making razors? When were they razor makers?
