The Jackson Artillerists of Philadelphia, after the appearance of the
regular dragoon cap plate in 1833 and the large crossed cannon of the
regular artillery one year later, lost no time in combining these two
devices to make their distinctive cap device.[117] It seems probable,
however, that the plate was adopted by other artillery units and
eventually became more or less of a stock pattern.
