David--You've built a very nice rifle!
I'm partial to New England Rifles rather than Kentucky Rifles. Unfortunately, the New England rifles do not have the mystique of Kentucky rifles. I only have one of each, New England and Kentucky, primarily because that's what I can afford at this late stage of life.
I believe that relative to quantities of each type built and surviving, the New England rifles tend to have survived more in original condition, in other words, original flint. I attribute that to the fact that the majority of New England Rifles were built for Militia members as evidenced by the fact that most were in .54 cal which was standard for U.S Military flint rifles of the period. The .54 cal was much too heavy for hunting in New England in the 19th Century as most of the big game in Southern New England had been hunted to the brink of extinction in contrast to the game in PA, VA, Ohio, etc. The Kentucky's, in my opinion, were mostly converted to percussion and used for many years out of necessity because they were needed to acquire the staple of life, food.
In any event I posted my one and only New England Rifle back in August 2019. Below are a couple photos as a reminder.
