I think wargames foundry had a small range of indians for that period or at least some would do.
Beware though they are more 25mm.
I think there is a film with Colin Farrell about that period.
it's right my friend.
The Foundry are back in production. And they are mixable with some converted warriors like nearly nude Foundry's Picts for example.
The movie is "New World" : Great pictures but a quite boring (too long).
A good mean to convert Conquistador and Elizabethan english into a new period.
The period is very interesting and very original.
I'll will use some Front Rank Malburian range to fit the job but not that same war. More Champlain 's in Canada period
around 1609....
