I didn't know there were earlier C-Mons made in the U.S. If they are like other U.S made razors I would say they are very high quality razors. U.S made razors are highly underrated.
Nope the fighting rooster has nothing to do with the original Hen and Rooster Co. When the original started to go under in the early 1970s A.G Russell bought the company and used them to make knives for his store. In the late 70s they folded and the company and all its machining was auctioned off. Klass of kissing cranes bought the name and made razors and knives under the brand for several years until he went under and more recently Frost Cutlery bought the Hen and Rooster name and sells knives and razors under it. The knives are made by Boker and the razors by Dovo. The original company made some of the best quality knives ever produced by the German's. If you ever come across some original Hen and Rooster razors buy them because they are priceless. I happen to know of a source but I ain't telling.
