Just prior to 1850 there were two Militia units in Philadelphia using
the letters "P G" to indicate organizational designation--the
Philadelphia Guards and the Philadelphia City Greys. This brass-cast
plate is believed to have been worn by the Philadelphia Guards, whose
buttons were marked "P G." The buttons worn by the Philadelphia City
Greys carried the three letters "P C G."[143]
