I don't know who made the kit, if it was a package, or ordered as parts to build the rifle. Ideas and suggestions are welcome.
Not sure that I can help you much. I would need to see close-ups of the parts to be certain. It appears you have a collection of parts and not an identifiable kit.
The lock looks like one that Dixie Gun Works used to sell if it has cast-in engraving. If it doesn't have engraving, then it might be a Griffith Tool Co lock. If the latter, it should have GTC on the inside of the plate.
The triggers look like those designed by Ron Long.
I can't tell much about the breech plug. The "5X" mark is on the bottom of the breech plug, not the barrel. The dash mark is a witness mark so the breech plug can be re-installed correctly if it is ever removed. The witness mark and the "5X" mark were likely made by the person that installed the breech plug in the barrel.
Some barrel makers would put their name or trade mark on a barrel flat. Others would put their mark on the face of the breech end of the barrel. In this case, it might be covered up by the breech plug.
If you were to count the number of lands/grooves and accurately measure the rate of twist in the rifling, it might indicate some possible barrel makers, but may not be definitive.
The trigger guard and butt plate are typical commercial parts available from a number of suppliers.
The lock mortise is so hacked up, I can't tell if it was ever pre-inlet. These stocks were available from different suppliers shaped but not inlet as well as shaped and partially inlet.
The set of Wayne Robidoux blue prints are the best that anybody has published and may be worth $25-50 if all six pages are there and in good shape. They are for a late Sam Hawken half stock rifle, though, and not the full stock parts set you have.
If the barrel, breech & tang, lock, and triggers are properly inlet, it would be time to install barrel lugs or staples for the barrel keys. Then you would want to drill, tap, and install the tang bolts and lock bolt. Butt plate, ramrod pipes and muzzle cap would follow, though it looks like the muzzle cap is already fitted.
