Thoughts on Pennsylvania/Kentucky Longrifle?

[Jasper Thompson]

I recently acquired this from a friend whose father passed away and I bought this longrifle along with two others. I’ve been doing a lot of searching and have been unable to find an exact match. First, has anyone seen this particular patch box? I’ve seen Tyron types like it, but not exact. Second, is there a way to pinpoint the year it was produced and by who? I can’t locate any distinctive markings on the surface.
