He Dog got it almost right. There were two companies (well one with two different names) that used the name N.R. Davis. N.R. Davis Arms Co from 1854 to 1983 and N.R. Davis & Sons Company from from 1883 to 1917. They finished up as the Davis-Warner Arms Corporation 1917 to 1930. Yes they made well made utility grade shotguns but remember these guns were designed fore black powder and later low pressure smokeless powder ammunition. They were not designed for modern high pressure smokeless powder shells and sorry to say they were made in the thousands, not millions.
