Here's an original halfstocked flinter for consideration:

This is actually a "rifle mounted smoothbore," of about .58 caliber:

I'm guessing that rimfire cartridge casing on the end of the ramrod is a somewhat later replacement, although judging from the apparent caliber of it, and the square-headed crosspin, it has likely been there for a while.
Anyway, this one was built by John Derr of Berks County, Pennsylvania. It sold at auction in 2019 for $3,500, and no, I didn't buy it. You can read more about it here:
John Derr Half-Stock It does appear to be an original half-stocked flintlock, but it isn't a Hawken.
Here is another old rifle to think about. This one is an early J&S Hawken fullstock, thought to be circa 1830:

This one is believed to have originally been a flintlock. In any event, the
lock was originally flint. However, it is a fullstock.
There have been some terrific flintlock Hawken-styled half-stock rifles shown on this thread. Beautiful rifles and real game-getters. I would love to have any one of them. As Herb said, if you want one, build it! My
only issue with halfstocked Hawken flintlocks is when or if they are presented as representing guns that actually existed. We just don't have a rifle, a written document, or unequivocal artwork (Rindisbacher notwithstanding) to support the existence of a half-stocked flintlock coming out of the Hawken shop.
Just for the sake of discussion, one other gentleman I don't think we've mentioned is John Palliser, an Irish sportsman who spent a couple of years on the northern plains of North America starting in the year 1847. His memoir,
Solitary Rambles and Adventures of a Hunter, was published in 1853. It is a great read. In the dedication, pages 13-18, he discusses his equipment of choice, including his firearms. There is too much to quote here, but his first choice, as an indispensible big-game hunter's arm, was a smoothbored double of 14 to 12 gauge. Next in importance was a "...single-barreled two-grooved rifle...," which I would assume used a belted bullet as described above. A search of the book failed to reveal any specific mention of Hawken or "Hawkins" rifles at all. In reading the book, it was clear that Palliser was shooting percussion guns, although he was familiar with flintlocks and in fact recommended a "self-priming flintlock" as the best weapon for buffalo running.
