CIRCA 1910, PENNSYLVANIA, NGP, F BATTERY, ARTILLERY, CAP BADGE, ENLISTED With red, white, and blue colored enameled keystone symbol in center with the Battery number above crossed cannons. Screw style attaching disc on reverse. In 1910, the NGP reorganized its artillery. All artillery then came under division control, which resulted in red, white, and blue keystone in crossed cannons. The National Guard of Pennsylvania (NGP) initially prescribed screw-back metal cap insignia that included enameled keystones of various colors on February 10, 1898. These insignia include a great many branches, but they were not issued or worn until after the NGP reorganization of late 1898 and 1899. They went on the enlisted men?s caps with straight sides that the US Army adopted in 1896, which replaced the earlier Civil War style forage cap. Photos show guardsmen also wore these enameled cap insignia on their campaign hats. International Buyers Please Note: We do not ship outside of the United States! No Exceptions.
