This is a command stand for Regiment Vierzet, a Walloon Regiment from Liege serving in the French army in the 1670s. Lacking information about the 1670's period flag, I've given it later colours from the Seven Years War from Dave at Not by Appointment Blog. Quite often French flag designs stayed the same, so it is plausible. The minis are from the excellent Warfare "officers with attitude" pack, excellently painted by Richard O'Connor. I'll write more about the unit when the other minis are based.
