This is an interesting question, as is Tim’s question regarding restorations in general.
In answering these questions, I think you need to consider the reason people collect them in the first place.
I’ll speak for myself, but I also believe that my thought’s are generally in line with the general majority of collectors of Kentucky’s, and just what makes a Kentucky a Kentucky.
From my point of view it’s a long barreled full stocked rifle, usually made as a flintlock, and for me, that’s what makes it a beautiful graceful rifle.
A short barreled half stocked percussion rifle just doesn’t fit the bill. If I wanted to collect that description of a rifle, I’d be collecting Plains Rifles.
Now whether to take a cut down stub of a Kentucky and stretch it back out to its original length and configuration and/or restore it is a question where not everyone will agree.
Needless to say, lot’s of old gun have been cut down, half stocked and percussinized, and whether to do it or not also depends on the particular rifle.
If the rifle has documented proof that Buffalo Bill killed a buffalo with it in the cut down percussion configuration, or some other such history, then leave it as is.
If it doesn’t, and most guns have no history at all, if the rifle has sufficient merit, then stretch it back out and re-convert it.
I mention sufficient merit, because getting a proper and well done stretch, flint conversion and restoration is not an inexpensive undertaking, but lot’s of collectors have had it done none the less.
So Why do it?
Because then the rifle will look like a Kentucky again, and if well done, can regain its beauty and original gracefulness again.
Generally speaking, it’ll also be worth more when it comes time to sell. The old ‘Ah yeah, make a buck’ mentality of some might find fault with this so the statement can be a bit of a sticky wicket, but spending a buck to make a buck and a quarter isn’t anything new either.
Also, and again generally speaking, a good and proper restoration will also give the gun a better chance of remaining in someone’s collection for many long years, and not be just thrown out in the trash by some uncaring heir down the road.
Needless to say, I don’t subscribe to adding patchboxes to guns that never had one, adding carving or inlays, making flinters out of original percussion guns, or refinishing guns to make them look new, however I see nothing wrong, and actually appreciate a well done sympathetic restoration.
