Take a look at Joe Meeks's "Sally". I have not seen the gun, but I have been told it is a two piece stock gun very similar to the Traditions/CVA/Jukar Kentucky with the two piece stock. This particualar gun does have an example you can point to.
I don't know about the Cabela's version.
I believe PC is about using the tech of the times, and has nothing to do with artistic reproduction of ever detail of a certain piece. A guy on a trek with a CVA Kentucky is using a tool very similar to what they used back then, and if he is shooting pyrodex that doesn't change a thing. He is still walking in their footsteps as close as he is able. A perfect copy gun does not enhance that, for me.
HC is about copies of what already happened. It is about copies of other peoples art and about being detail oriented about items. It has nothing to do with survival skills, treks, hunts, or any other part of the hobby I enjoy except sitting around BS'ing. It doesn't make the guns easier to fire, maintain, more accurate, or even more pleasant to carry. It doesn't help you collect dinner or defend yourself. It is simply there so guys can get together at gatherings and put down everyone else's gear. It serves no other purpose that I have been able to find so far.
Those are my thoughts, today.
