AH welcome to one of the most famous, or perhaps infamous, rabbit-holes in all of flintlock riflery. Beware, for this rabbit hole has rabbits that are killers with "
nasty, pointy teeth"

Short answer, you probably want to copy the
Edward Marshall rifle, if you want what is currently thought to be the best surviving example. Whether that rifle is a true example of the majority of what you might have observed back then, is another matter. Some say the
John Schreit rifle is a better choice. James Fenimore Cooper wrote about
Killdeer, but another point of debate is would
Hawkeye have had such and if yes, would his companion
Hurry Harry March have also had one.?
Here is an article about rifles in general during the F&I War:
Rifles of The Frontier Partisans ; Rifles in The French and Indian War
This accompanying article is about the Edward Marshall rifle itself:
The Edward Marshall Rifle
The "nice" thing is that you can adjust some of the characteristics to suit you, and not necessarily be wrong in what you have when done.
