This is a bronze badge won in 1922 (first year of issue), by a NCO in the Washington National Guard.
This badge was created in 1922, and was awarded for rifle marksmanship.
It is named to “Corporal Bill B. MacAdams, Batt. C. 146th F.A. – Wash. N.G. – 1922.”
The oak leaf brooch indicated an Army level competition, and the color light blue indicated this badge being an army “Team.”
This unit was attached to the 41st Infantry Division.
This all may have something to do with the 161st Infantry consolidating with the old field artillery battalion of the Washington National Guard, into the new 146th F.A. in 1921.
Made from bronze, and measuring 2 1/4 inches high, it has a pin brooch, with locking ring.
Excellent condition, and scarce being awarded in the first year of the badge’s issue.
