The original catalogue description states:
The Young Guard was formed to increase the numbers of Imperial Guard Regiments on which Napoleon greatly relied and also to be eventually recruited into the ranks of the Old Guard.
The Young Guard wore corded shakos, short tailed coats, waistcoats,knee breeches and short giters.
The Tirailleurs wore round pom-poms in their shakos and had pointed shoulder straps.
The Voltigeurs had tall plumes in their shakos and wore fringed epaulettes on their shoulders.
Note: the Young Guard Officers FN/70 and FN/74 had the same patterns of uniforms for Tirailleurs and Voltigeurs, only the colouring differed.
