The Spanish small enterprise Tercio Creativo terciocreativo.blogspot.com offers on download a set of swashbuckling rules '1650' -in Spanish, but has a good press among the few 'hispanophonic' French players who tried it.
According to current fashion these rules are intended to support their growing miniatures line.
My decades-old wargaming experience being rooted in 'Historicals' (well, almost: does Hyboria using mainly historical armies counts as such?), the concept of a compulsory (or almost so) association of a background with a set of rules and a range of miniatures strikes me as… odd. While *at the limit* I can understand a 'ready to play' boxed game (specially if the minis included are painted), otherwise I resent it as a copy of the "GWshopping is a compleat hobby, don't spend a cent elsewhere" marketing trick. For me a GW fanboy knows the Illumination when he realizes that he can play in the WH40k rich setting with Hesslefree minis and Stargrunt rules!
So much the more that in this case the figurines -which look quite good- are of the odd 35mm size, incompatible with practically any other range.
Then if the rules and the decor elements are god, one can always play with other miniatures -of course.
And one does not have to feel restricted to the 1st half of the 17th C. This is indeed the period par excellence of swashbuckling literature: French '3 Mousquetaires' and 'Capitaine Fracasse' are set during the reign of Louis XIII, and our 'last' popular swashbuckling novel, 'Le Bossu', set during the French Regence, looks almost 'marginal'.
Yet, when in the mid "70 I gathered a RPG and WG group, since for tabletop battle the members preferred to play Ancients, in order to have some (miniatures-less, but better than nothing!) games in my favorite period, the 'Lace Wars', I 'GMed' a RPG campaign set in an 'alternate' 1745 France, where the Fronde en.wikipedia.org/wiki/Fronde had partly triumphed, so the central power had no more control, and the great noble families enjoyed the same freedom, as in 'historical' 1625 France.
We used the basic D&D rules (the brown box + the 2 first supplements) without magic (and combining thieves with monks!), complemented by the excellent 'Flashing Blades' rules link (still supported link ) to 'proportion' gunpowder weapons with cold steel ones, and also for some colorful elements of background and exciting scenario ideas.
Thus if you like tricornes and justaucorps and already have corresponding minis (as most Pirate plyers do), you can perfectly play 'traditional' / 'typical' 3 musketeers-like swashbuckling games with your favorite figurines..
