There are several possibilities here --
N.R. Davis & Sons of Assonet, Mass., was one of the first U.S. manufacturers of breech loading double barrel shotguns. N.R. Davis was taken over by Warner Arms Corp. around WW-I. Warner moved the assets from the original factory in Assonet, Mass. to their plant in Norwich, Conn. in 1919, and became Davis-Warner Arms Corp. They continued to manufacture Davis doubles until about 1926 when they closed the plant and tried their hand at importing guns from Belgium. So, there may be some Davis doubles marked Warner, and yes Ithaca did "trade brand" there Lefever Nitro Special, their Western Arms Long Range Double, and even a few of their Flues Model Ithacas. Ithaca Gun Co. quit "trade branding" their guns about 1932.
