Funny that on the average AWI
aficionados are as...
hysterically historical as '
Napoleonics'; while 'Lace Wars' players are generally far more tolerant to 'departures from strict historicity'. Wonder if it's somehow correlated with the different types of warfare: civilians in uniform maddened by ideological / nationalist passion rather than cold professionals waging a 'war without hatred'?

As for the original query, search F&IW (and possibly AWI?) ranges for a 'White', preferably French (no rank sash) officer in 'field' dress with Indian leggins; unfortunately such minis as a rule represent
Compagnies Franches de la Marine without lapels. F&iW "provincials" may have lapels, on the other hand, and some are depicted with leggings rather than 'European' gaiters

Try to post your question on the LAF "Pikes, Muskets and Flouncy Shirts" board where the F&Iw is dealt with (under another title not be culprit of 'cross posting'), or perhaps even better on the
'18th C. Imagi-Nations' board of The Miniature Page : you are far more likely not to be derided, and to get a positive reply, there.
