Very nice rifle Steven and I certainly can understand your excitement to be getting it.
On subject but from a different angle what fascinates me is what the rifling head and cutter looked like. In the mid-19th century machining/manufacturing, albeit skilled and precise, was archaic compared with 20th and now 21st century machining. Even at very light cuts the size and shape of the rifling grooves would require a fair amount of cutting force to scrape them out. And in the days prior to high speed steel tool sharpening and maintenance would be quite time consuming and a big deal.
And along the lines are the tools used for cutting the mold. The cherry shape needed to cut the mold cavity would be unique and fragile to cut the long sprue stem. If you have ever cut bullet molds you will understand my awhh at the machinists skill.
