Found this in an old dresser. Marked sterling, hallmark has crown w/ the letter C on the left and the letter M on the right with a symbol in the center of the crown w/ 3 numbers under the crown. It is slightly larger than a quartet as seen in picture. Am unable to find any information nor anything like in through extensive internet search. Any help with identification greatly appreciated.

Mystery Solved

    could be 925 under the makers mark, further confirming sterling silver content.... and maybe I'm reaching for numbers but under sterling maybe thats a 1000, like 925 part silver out of 1000 parts. makers mark is a trickier one to find!

    If it is marked sterling, which it is, it means it is American and that it is 92.5. I will search my resources for a manufacturer.

    Providence Rhode Island
    (Campbell went on to design for Manchester)

    See the page above to confirm, it is the third mark down from the top left. Yes, it is a 925 printed below the logo.
