No problem. As I said in another post, Osprey have some good books on the armies of the era (well pretty much every war in history), I have the books on the French army, if you want me to I can scan in some of the pictures and PM you although as the Osprey illustrations are popular you may have already seen them.
One thing as well with uniforms is that they tended to fall apart pretty quickly (a private would be lucky to have his uniform survive one year), one reason why the British soldiers fighting in the War of Independence modified their uniforms so that they had more material to patch them up (also because the tails kept getting snagged on things).
