This is a well used U S Marines clock. It runs very well and dates from about 1947. It is  Nickel Plated with several rust spots and a flake is missing  1/4" on the outside ring. It is possible to have the Nickel plating redone to make it look new, however it is pretty cool that it shows its age. The Case and Movement have the same Serial numbers.

With its large  6" dial it is a larger Clock and a little harder to come by.
