Originally the only headdress worn by when mounted, was the blue forage cap.
 As a marching band, all RA bands wore the busby.
In 1894 a new style black sable busby was introduced (the earlier busby having once replaced the shako from c. 1850 until the end of the 1860s) with a scarlet bag on the right, and a brass grenade on the left, which held a red cut feather plume.
The busby was held in place on the head by a brass chin chain, on a black leather strap.
The busby (originally the headdress of hussars) became the correct headdress for all mounted ceremonial duties, as well as for marching band.
At some time during the late 1860s, the familiar modern helmet, with a ball replacing the usual spike (similar to that worn by policemen) appeared, which remained part of the uniform until 1894. [

The tunic was not worn on horseback: the patrol jacket of the royal artillery was worn instead.
The patrol jacket was made of navy blue cloth with a scarlet collar edged in gold lace; at each side on the front were gilt grenade badges.
The front of the jacked was piped with yellow-ochre rope (later replaced with gold Russia braid) and was fastened by hooks and eyes.
 The shoulder straps were gold cords held in place by a gilt button at the collar.
The cuffs of the jacket were navy blue with an Austrian knot in gold cord.
The pouch belt (worn over the left shoulder) was white leather with a large black patent leather pouch (for carrying music cards, on the flap of which was fastened the RA gun badge.
The waistbelt was also of white leather, with a brass snake-hook clasp.
The RA band-sword [see "The Royal Artillery Band" (¶1) above] was not worn, and so the sword slings were linked together.
Peculiar to the Mounted band were the girdles (similar to the broader stable belts of today) that were worn together with the pouch belts.
 The girdle (introduced in 1904) sported the RA colours, red, and blue, and was fastened with brass olivettes and loops (originally at the wearer's front, then at the side).
A year later, a wider version, with a central stripe in blue was introduced to the RA Mounted Band, and later into the RA bands in Dover, Plymouth, and Portsmouth.
In 1920, it was finally introduced into the RA Band at Woolwich.
A more recent girdle design, still to be seen worn by some of the musicians in the 1980s, featured brass clasp-fastenings, adorned with the RA musicians' lyre.
White leather gloves with clay-piping were uniquely worn in the Mounted Band (those worn in the other bands were of white brushed cotton).
The riding breeches were navy blue with a broad scarlet stripe down the outer seam.
 The riding boots were of black leather and spurs were held on by straps.
In undress, a blue forage (pill-box) cap with a gold lace band was worn.
When marching, the mounted bands wore the standard officer pattern 'George' boot with 'dress' spurs fixed to the heel with screws, rather than the 'box' spurs as worn by officers.

The silver-plated kettledrums were covered in a dark blue 'bib' (drum banner).
The harness was of brown leather with a brass-studded bridle and a breast plate of brass, depicting the grenade badge.
The shabraque was likewise decorated.
The third, or 'foot rein' was fastened onto the stirrups.
The bit reins, and bridal reins rested in the neck of the animal.
The saddle was the standard army pattern.
So as to make a distinction between the two bands, no kettle drum bibs or shabraques were used by the 'Mounted Portion' at Woolwich.

In 1899, in anticipation of the start of the new millennium, the brass 'bomb' plume holder was moved to the front of the Royal Artillery busby, and the plume was changed from cut feather to scarlet horsehair.
