Surprised that this rifle has resurfaced here in the discussion. I did not comment earlier as it was up for auction, but now that has been sold, guess that I can tell you what I know about it.
Am pretty certain that this gun was in a large Santa Barbara collection which I had the privilege to see and handle most of the pieces many times. So, am still pretty certain that this rifle was in the group. It is an early piece made by Jacob Dickert and is signed as such. The butt stock is quite thick and all of the wood is sound. Not sure how it came to be associated with King's Mountain, as I never heard Richard say that specifically. He may have felt that it was of an age and type that was used there. Another feature of the rifle is that it had only one lock plate bolt. The front was a screw to hold the side plate firm. My first impression was that this was wrong. It should have had the obligatory two bolt configuration. To me it was rather a late made gun built to look old; to resemble a 1770s gun. Much later I learned that some makers in England in the mid 1700s were playing around with the 'one bolt does it all' concept, and factoring that into the situation, the gun is in reality a 1770s product. Now I see that it has grown a second bolt and I had in fact heard that had taken place. A recent owner had the same reaction that I did initially and had it changed. I later had the satisfaction of pointing it out to the individual at a KRA meeting and got a shrug for my revelation.
The rifle was nominated for an NRA silver medal award at the Phoenix annual meeting and I was in attendance when it was presented. My overall impressions are that it is a great early Dickert rifle and when I finally win the lottery, I am going to buy it, and I'm going to have that darned front lock bolt reversed to what it should be!
If you look a the earlier B & W photos you can see the way it appeared originally and when the gun was in hand it was very obvious.
