If I had to date this item, I'd place it in the mid to late'50s. The method of construction leads me to believe that it was most likely a locally made, "sand cast" item, produced for sale to the American servicemen, presumably by some enterprising locals. All I can say for sure is that I've personally never seen or come across another one. It is non-magnetic, and appears to be all solid brass.
The round section itself measures 10 7/8 inches in diameter, and the eagle itself, which is secured to the round section via two brass slotted screws, measures 9 1/2 inches from wing tip to wing tip, and roughly 6 inches tall. The overall height is 16 inches. It can be suspended via a single brass loop, which is cast integrally as part of the eagles forward facing wing.
There is just a slight bit of "flatness" to the edge at the 6:00 position of the disc, otherwise, the condition is excellent w/ a very nice, un-touched brass patina. What an impressive, unique gift this would be for any 1950s US Air Force / Korean War period veteran, or fabulous addition to any Korean War / Cold War vintage collection or display!
