On introduction in 1923 Hunter Arms ads, and later catalog listings, referred to the gun as the "L.C. Smith Long Range Wild Fowl Gun"
Hunter-Trader-Trapper August 1923
1925 just "Long Range"
According to Dr. Jim's Production Records "WILD FOWL" was not stamped on the barrel lug until 1940. I would note that the barrel does have the barrel loop support often, but not always, found on LRWF guns
