Between wars STERLING badge made by BALFOUR.
According to William H. Emerson’s book on Marksmanship In the U.S. Army, this is a type of badge that was worn interwar period. This is no mention of this particular type, but the similarities are there to place it in this era. The badge is made of Sterling, by “IGB” (BALFOUR). It has a safety lock for the pin bar, another post WWI feature.
The badge is 1 3/4 inches at the widest, (crossed cannons are 1 1/4″). There is red enameling in the center with the Coast Artillery shell. The brooch reads, “I CRACK SQUAD.”
It is believed that this type of badge could be for either ROTC, National Guard, or Regular Army.
This is the first one of these we have encountered. Fine condition.
