Got this at an estate auction, the bottom is marked "STERLING" with Cast Aluminum underneath it. I've been searching but cannot find a company name Sterling that makes this type of stuff. Anyone have a clue? Also no idea how old this is either or where it would be used, or what country. This kettle is pretty large, it's 13.5" long from spout, and 10" wide diameter measuring from bottom, and 8" tall bottom to top of lid. If anyone knows of this maker please let me know. Thanks!
