Noailles French Cavalry Regiment

This Regiment has, unusually, an all-red coat, similar in colour, if not style, to the Gendarmerie.  It was raised in 1688 and, in some sources, it is referred to as d'Ayen, another ducal title
used by the Noailles familly. I had no idea about the drummer livery but I have gone with a yellow-red combination which was on the coat of arms.
