Although the Regular riflemen wore a diamond-shaped plate from 1812 to
1814, this shape does not appear on Militia caps until the mid-1820's.
It was a common form through the 1830's, but since it was always made
as a one-piece die-struck plate it became out-dated in the late 1830's
when the composite plates came into vogue.
This plate, struck in brass and bearing the eagle-on-cannon device,
must be considered a stock pattern available to many organizations.
Insignia struck from the same die could have been easily made into
shoulder-belt plates as well.
