I'm pretty sure I have posted the images below somewhere already but I'll be damned if I remember which topic, so here we go again.
The first pic shows a typical French musketeer from the late 1660's and 1670's with crossed
bandouličres, one for the apostles and one for the sword :

Next is a side view of the short-lived 1683 equipment now worn on the waistbelt except for the powder flask (the length of the man's musket is obviously grossly exaggerated here) :

This is the improved
fourniment introduced circa 1686-1688 and pretty much universal among front-line troops by 1690-1692 : it now has a protective leather flap which covers the powder flask and bullet bag. Note the bayonet scabbard protruding from under the flap:

As Iain said, the outdated crossed bandoliers remained in use among second line troops (particularly city and provincial militia units) until at least late in the C17th as issuing them with the new equipment was not considered a priority.
