I thought that from 1791 up to 1804 (?) there were no voltigeur companies in the line battalions. At least not formally.
So they would wear informal dress so probably normal line dress with some additions (green/yellow plume with maybe green/yellow epaulettes, hunting badges etc).
Just want to let you know, that we (Alde Garde) will put on a demo of the Nine Years War with BLB at the coming Crisis show. Maybe we see you there.
Greetings Jan
