Hello,
the discussion on the "usefulness" of these little men on Streletz forum is justified in that sense that pikemen in the French army were really out of service at the time of WSS. Mainly, they saw their service end by around 1690. At that time the tricorn was not yet worn by the French, but a round brimmed hat. Some also wore helmets.
But as Graeme points out, the figures are nice enough and it remains easy to assort the hat or make head swops and you obtain useful pikemen for the many earlier wars of the great Sunking - period from 1660 to 1690. Here, the bad point is that there are few musketeers, mostly by Mars and these figures are rather stocky.
2 pictures to illustrate the appearance of French pikeneers for 1660 to 1690 period.
Greetings
Michael
