There are a few different companies making Three Musketeer figures, but for me the best by far are the 40mm range from Eureka Miniatures (and no, i don't own shares in the company and i am not recieving kick backs for all the postitive feed back i give about Eureka).
The large scale figures have amazing detail and even look like the actors than played the roles in the 1970's film "The Three Musketeers" and the sequal "The Four Musketeers".
Not only are these figures fantastic, but there is plenty of scenery you can buy such as tables, barrels and even geese.
If this wasnt enough to tempt those wanting to wargame the Three Musketeers, then Eurkea Miniatures also has a free set of rules you can download from their site. These are a fantastic set of rules - very easy to learn and play.
For an overview of the rules, the actual rules and some photos of the minitures go to this link:
And All For One
There is also a forum moderated by the writer of the rules: Anubis Studios It is unfortunate that the forum isnt that often visited, but with more people playing the game i am sure that would change.
Any way, here are some photos of two figures i have painted: D'Artagnan and a Cardinal Guard
