There's not a lot of information available and most authors disagree on that. Carey's American Firearms Makers says the company was in Norwich Ct from 1855 to 1894 and made single shot percussion and metallic cartridge rifles. Vorisek's Shotgun Markings lists 4 different names, W.H. Davenport Firearms Company, W.H. Davenport Arms Company, Davenport Arms Company, and W.H. Davenport & Co., and gives dates from 1878 to 1910. The Standard Catalog says they made single barrel shotguns from 1880 to 1915 and single shot rifles from 1891 to 1910. Traister's Antique Guns says they made single shot and double barrel shotguns in Providence, RI. The Official Price Guide to Antique and Modern Firearms says single and double shotguns in Providence, 1880-1883, and Norwich, 1890-1900.

Answer This answer was borrowed from a thread on the GunBroker.com website. The answer was posted by a gentleman who is a collector of old shotguns. I do not claim authorship nor authoritative knowledge. There were two "WH Hamilton" shotguns. From c.1875-1883 or so, the shotguns were imported from Belgium. They were external hammer shotguns of average quality for the time. In the early 1900s, Thomas Leary was an active importer of these guns, now made by Dumoulin with the WH Hamilton tradename. They were similar to the earlier ones, but with some engraving on the locks. The WH Hamilton tradename was finished when Leary closed up in 1904. Dumoulin may have continued until the 1930s. As you read so often in posts regarding these old guns, it is absolutely NOT safe to shoot with any type of modern ammunition.
W.H Davenport was a minor shotgun manufacturer that produced primarily single shot 10 & 12 gauge shotguns between 1870 and 1910. They built some double barrel guns under the "King Nitro" trade name, which were sold by mail order hardware companies. Acme was another trade name for guns produced by W.H Davenport.
NEWPORT was a tradename used by the catalog/hardware giant Hibbard, Spencer& Bartlett Co (HS&B) in Chicago up until WW2. The single barrel guns were made by various contract manufacturers such as Iver Johnson and WH Davenport.
