Hi Bethof welcome to the forum.
Sorry, I hate to disappoint you, but the ladle is not made out of sterling silver but made out of a non precious base metal and only covered with a thin layer of silver or silver-plated. The ladle is made by: Elkington, Mason & Co between 1842 and 1864, in Birmingham England U.K.
