L'Essor's better known safety razors are it's wedge blade SE and ultra desirable Le Supreme Adjustable. This razor, vintage unknown but 1930s presumably, features open combs offering different levels of aggression on each side -- medium aggressive and aggressive. Weight is 59g. It is a supremely efficient shaver based on my initial experience. This example I acquired in apparently unused condition. There is another Single Ring type handle version, and perhaps a three piece with a slightly different handle. This handle is extremely similar to the one found with my Famex cage razor, but it is not identical. Any additional information regarding these razors is appreciated!
