In 1850 the regiment was given a "trumpet" hat device. Officers were to wear "a trumpet, perpendicular, embroidered in gold, with the number of the regiment, in silver, within the bend."[83] This trumpet is also known in metal imitation-embroidery. The prescribed regimental number, which is illustrated in the Horstmann publication of the regulations (pl. 15), is not included on the device, probably because there was but one such unit in the Regular Establishment.

The same general order that gave rifle officers a gold-embroidered trumpet prescribed for enlisted men a similar device to be of "yellow metal." This insignia lasted but one year for the men in the ranks, being unmentioned in the 1851 regulations.
Shoulder-Belt and Waist-Belt Plates
Oval shoulder-belt plates were worn by American officers during the War of the Revolution, but no extant specimens are known. Highly ornamented or engraved officers' plates for the period after 1790 are in several collections (fig. [53]) and others are illustrated in contemporary portraits (fig. [54]). Just what year shoulder-belt plates were issued to enlisted personnel is unknown, but their use appears to have been well established by 1812. The uniform regulations for that year specified swords for sergeants of infantry to be "worn with a white cross belt 3-1/2 inches wide," but nothing was said about a device on the belt.[84]
