Yes, Camillus acquired Western in 1991, I believe. Since they own the IP and the rest, they are the custodians of the Western archives, the "go-to people" for questions on them.
Questions such as: Many Western blade patterns are shared with Schrade Cut Co., Imperial, Schrade Walden, and several other companies. The only way to identify some of them as Westerns positively, is from the double pommel pins and uper and lower exposed tang, a result of the 1934 H.C. Platts patent tang. Did Harlow ever license the tang patent to another manufacturer, or was it always closely held by Western?
