Age of this J.Wiss & Son razor?

[xJesse]

How's it going. I recently purchased this razor from Ebay. 1st razor, I work in Newark so I thought it was an interesting choice and it has so far worked well.

My question is on the age of the blade. J. Wiss & Son was open from 1885 - 1969, which is almost a century. Does anyone know a more precise age, maybe within 10 years or if it is over 100 years old? The only thing I have is that it is still squared, which if I recall, was going out of fashion near the turn of the 1900's.

Any help is appreciated. Thanks.
