I have an old salesman's sample cannonball safe. Markings on the base of it as follows: Ely-Norris Patented . Manard Mangaues Steel Safes. York Safe and Lock Company, York Pa. L.F. Dow Company Distributors for Northwest. St. Paul Minn. Can anyone give me an idea who I could contact to get an approx value or even to sell it? My wife and I have retired and are downsizing. Thank you.
