I thought I'd breath some life into this area of the forum, and see if we can get more action with the Rev War
Here is a nice 1763 series Charleville, with some features of the 1768 revisions. I believe France gave us around 48,000 during the war. Many of these were re-stocked during and after the war in Cherry. This one appears to have been restocked and lacks the middle barrel band. It still retains the 44 1/2" barrel, in .69 caliber.
Orders were given in 1777 to mark the arms owned by Continental Congress. Some studies have been done to date the different brands/stamps used. These marks are believed to be late war or done postwar at an arsenal, possibly when it was restocked.
The 1768 Charleville would be the model from which the armorers at Springfield would base the first US military model weapon, the M1795 Springfield.
It's been a while since I've brushed up on my 18th centruy weapons, so feel free to chime in with more info, and post your guns to share!
