Sorry about the two-year delay in answering your question. I'm a newbie here; just saw your post five minutes ago. Afraid I cannot identify your "Royal Ejector" shotgun, but I have one that's identical to the pics you posted. Used to belong to my great-aunt, who lived on a farm in south-central Maryland with no running water or electricity. The shotgun lived behind the door to the North Porch and was always loaded. Don't know exactly how old it is, but my earliest memory of the gun is from about 1938, and I'm pretty sure it was nowhere near new even then.
