An illustration in _U.S. Military Magazine_[114] shows this plate being worn by the National Greys; however, with such a nondistinctive center ornament as the rosette of six petals, it must surely have been a stock pattern sold to many different organizations. The sunburst proper is struck in brass, as is the rosette, and each of the rays is pierced at the end for attachment. The rosette is affixed with a brass bolt, also for attachment, which must have extended through the front of the cap. [Footnote 114: May 1839, pl. 7.] CAP PLATE, ARTILLERY, C. 1840-1850 _USNM 60333-M (S-K 89). Figure 141._ [Illustration: FIGURE 141] This plate is struck in very thin brass. The combination of devices in the design, especially of the cannon and cannon balls, indicates that it was probably made for Militia artillery. Its shape suggests that it may have been worn high on the cap front, with the sunburst serving an added function as a cockade of sorts. It was very probably a stock pattern. CAP PLATE, MOUNTED TROOPS, C. 1836 _USNM 60319-M (S-K 75). Figure 142._ [Illustration: FIGURE 142] From the size of this brass plate it can be assumed that it was worn without other ornament on the front of the round leather cap associated with mounted troops. The upper portion of the shield bears 8-pointed stars, an unusual feature. The arrows in the eagle's left talon point inward, a characteristic of eagle representation between 1832 and 1836. The plate is known both in brass and with silver finish. It was probably a stock pattern issued to both cavalry and mounted artillery. CAP EAGLE, C. 1836 _USNM 60391-M (S-K 147). Figure 143._ [Illustration: FIGURE 143] This brass eagle was worn in combination with backgrounds of full-, half-, and three-quarter sunbursts and as a single ornament on the cap front. The inward-pointed arrows in the left talon place it in the 1832-1836 period. Known in both brass and silver-on-copper, it was a popular stock pattern sold to many units. CAP PLATE, C. 1836 _USNM 60381-M (S-K 137). Figure 144._ [Illustration: FIGURE 144] Struck in copper, and silvered, this eagle, which is very similar in design to that prescribed for the Regular Establishment in both 1821 and 1832, was made for Militia infantry from about 1836 to perhaps as late as 1851. Specimens struck in brass are also known, and the same eagle is found on half-sunburst backgrounds. It is quite possible that this is the eagle illustrated in the Huddy and Duval prints as being worn by both the Washington Blues of Philadelphia and the U.S. Marine Corps.[115] [Footnote 115: _U.S. Military Magazine_ (February 1840), pl. 28; (November 1840), unnumbered plate.] CHAPEAU ORNAMENT, C. 1836 _USNM 60287-M (S-K 45).
