This three-quarter-sunburst plate with the monogram "I D" applied in
silver is identical to one on a brass-bound dragoon cap in the
national collections carrying in its crown the label "Irish Dragoons,
Brooklyn, N.Y." (USNM 604691, S-K 837). It is typical of the two-piece
sunburst-type plates and was probably worn until the 1850's. The plate
was attached by means of two looped-wire fasteners that were run
through holes in the helmet and secured by leather thongs.
