There was no Victor Ejector gun company. Your gun is known as a "Trade Brand Name" shotgun. A "Trade Brand Name" shotgun is one that was made by a major gun maker (and before 1940) for and was sold by a wholesale sporting goods dealer, a retail chain store, or an independent seller who chose the name to go on the gun. Guns with the name VICTOR EJECTOR were made by the Crescent Firearms Company of Norwich, CT (1892 to 1930+) for and were sold at wholesale by the H & D Folsom Company of New York City a large wholesale, retail, jobber and distributor of guns and sporting goods. The records of Crescent Firearms were destroyed in a scrap paper drive in 1943 during World War Two. H & D Folsom owned Crescent Fire Arms from 1893 to 1930 and what ever Folsom wanted, Crescent made. And what they wanted was a lot of inexpensive (read cheap) shotguns fast.
