Sorry for the confusion, my comment to Dennis at the TN/KY Rifle Show was based on my experience of always seeing the original "Capital Rifle" as it is referred to in the showcase at the East Tennessee History Center's museum. A little investigation has yielded the following explanation.
The original rifle was taken to Nashville last week, there are several pictures on Facebook of Tennessee Legislators being photographed holding the rifle there. In the meantime, the copy Dennis photographed was placed in the case for the museum's visitors to see. After a good laugh about my character and reputation being disparaged and besmirched on the Internet over the situation, the owners assured me that in the future when the original rifle is not on display, a note will be placed in the case identifying it as a copy.
