This plate, which formerly belonged to Gen. William S. Harney when he commanded the 2d Dragoons in 1836, is identical to the general and staff officers' plate of the 1832 regulations except that the letters "U.S." have been replaced by the letter "D" in Old English, as prescribed.[94] [Footnote 94: General Order No. 38, Headquarters of the Army, May 2, 1833 (photostatic copy in files of the division of military history, Smithsonian Institution).] WAIST-BELT PLATE, NONCOMMISSIONED OFFICER, 1836 _USNM 604114-M (S-K 268). Figure 85._ [Illustration: FIGURE 85] The 1835 uniform regulations replaced the rather impractical S-hook NCO belt plate with a "round clasp" on which the branch designation was replaced with the raised letters "U S." Similar in over-all design to the 1821 officers' plate, round with outer ring, these plates were rough cast in brass and had a stippled surface. WAIST-BELT PLATE, NONCOMMISSIONED OFFICER, 1836 _USNM 604114 (S-K 270). Not illustrated._ This specimen is very similar to the preceding plate, but it is of a definitely different casting and is generally heavier in over-all appearance, the inner ring is much more convex, and the letters "U S" are raised only slightly and spread farther apart. SHOULDER-BELT PLATE, OFFICERS, 1839 _USNM 40886. Figure 86._ [Illustration: FIGURE 86] The 1839 uniform regulations specified a shoulder belt (rather than a waist belt) for carrying the sword, with a "breast plate according to the pattern to be furnished by the Ordnance Department." This plate, which was worn by Capt. Erastus Capron, 1st Artillery, an 1833 graduate of the Military Academy, is believed to be that specified.[95] The specimen is rectangular with beveled edges, cast in brass, and has the lines of a modified sunburst radiating outward. In the center, within a wreath of laurel, are the letters "U S" in Old English. Both the wreath and letters are of silvered copper and are applied. The plate is attached by three broad hooks rather than two studs and a hook.

Not illustrated._ This plate is almost identical to the Capron specimen above except that the letters "U S," instead of being in Old English, are formed of oak leaves.
