This brass-cast plate with its letters "S N Y" for State of New York is copied directly from the 1836 plate for noncommissioned officers of the Regular Establishment. The example is the oldest known use of the letters "S N Y" for New York Militia. In later patterns, the letters "S N Y" and "N Y" were placed on rectangular plates and on oval plates worn on the waist belt and on cartridge boxes just prior to and during the Civil War. Small square plates with silver, Old English letters "NY" are included in the 1900 catalog of the Warnock Uniform Co. of New York as regulation pattern that year for National Guard officers.
