Yes, I know that 2nd edition AD&D has a Swashbuckler as a fighter sub-class. Mine was created independently of this one, though after hearing about it, I discovered that the two were very similar. It rather stands to reason that 2 "musketeers" might come out similarly. Use mine or use theirs, it's a fine class either way. The following is taken directly from my write-up of the class that I use in my campaign.
The swashbuckler
is a sub-class of fighter. These rogues tend towards a chivalric and pompous
lifestyle, and may be of any Lawful alignment. Humans, elves and half elves
may be swashbucklers. The average swashbuckler will be found wearing fancy
clothing, including hats with plumage. They tend to prefer one-handed swords,
favoring first the Cutlass (treat as a Glaive with regards to damage),
then the Scimitar, and finally, the Longsword. To a man (or a woman), they
disdain the use of shields in combat, preferring either a single sword
or a sword and dagger when fighting florentine. Swashbucklers may opt to
use on non-weapon proficiency slot to effect a quick draw and ready move
(q.v. Iaijutsu, Oriental Adventures).
Most of this
class will wear fine clothing with padding, giving them an armor class
of 9. They also have an advanced dexterity armor class bonus system, which
allows them to use quickness instead of armor to protect themselves. This
advanced AC bonus is negated if bulky or fairly bulky armor is worn. The
following table shows their advanced AC bonus, based on their dexterity,
and their attacks per round, based on level.

Swashbucklers
have minimum required stats of 15 dexterity, and 14 charisma. They also
gain a +1 to their initial comliness score. They use the fighter's table
in the Unearthed Arcana when a human character is generated. They can opt
to become Bards, with the appropriate additional training. They begin their
career with 1-2 additional languages already known, and prefer other human/demi-human
tongues if available (french, spanish, elven, etc.).
Swashbucklers,
while a member of the fighter class, may have a maximum +3 constitution
hit point bonus. Saving throws and THAC0 are the same as fighters.
The swashbuckler is a stand-alone class, and may not be combined with other classes as a multi-classed character. If one is psionically endowed, he may take Psionic as a secondary class, regardless of race. Swashbucklers may not change class to Magic user.
Members of this class begin their career with certain non-weapon proficiencies. These are; Boating, Riding land based, Dancing, and Stellar Navigation. They can also Pick Locks and Find Secret Doors as a thief of two levels lower than their present level. Evil swashbucklers tend to be pirates and privateers.
