Probably because everyone copied the list trade names on their web pages from the back of the Standard Catalog and it isn't there. The Catalog only lists 2 Enders model names, but Vorisek's Shotgun Markings - 1865-1940 lists 13, including the Royal American which was a Crescent Model 60. All were marked for Shapleigh Hardware of St Louis.
