Hello from Seattle. Your forum caught my eye while researching some family military service that included Union Army, Boer War, WW1, WW2, Korea, and Viet Nam.
I am not a collector but have numerous odds and ends from my father's USN AWS assignments during the Cold War in Western Pacific from 1958 t0 1968. Abilene 10 was his call sign while aboard the CVS-10 USS Yorktown.
A junk store find in Seattle from 20 years ago and am wondering if it is related to the Boeing war effort. These appear to be the same size as the WW2 fat ribbons. The mounting bar is zinc plated.
