The Paragon was a high grade shotgun made by the Baker Gun & Forging Co. of Batavia New York. They went out of business, I believe, sometime during the early 1930's. I'm supprised that the firearm does not have the the manufactures name stamped on it somewhere. If this info is not stamped on the firearm and this gun did not start its life as a high grade gun ( meaning quality checkering and high grade wood) then it may be a knockoff trying to capalize on the name and I'm probably all wet as to its manufacture. Since writting the above I've discovered that their was indeed a firearm named "Paragon" manufactrured (or imported) by the H & D Folsom Arms Co. of New York N.Y. This Co. would put any name you wanted on a gun if you would pay the costs involved. This same gun could be sold to someone else with a different name on it. The ref. I have for this Paragon implies that the gun had exposed hammers and damascus barrels. Which, by the way, may have been true of some (but not all) of the Paragons made by Baker Gun & Forging. My bet is that if this is obviously not a high grade gun that yours was from H & D Folsom Arms Co.
Side-by-side shotguns are still manufactured.
