If I was close enough I would definitely check this out.
The Sheetz rifle built for Ross (at some point prior to January of 1815 when it was used in New Orleans) is not what many of us think of as a "typical" Golden Age rifle.
It has a 42" barrel (ok, that's typical) but it's a 38 caliber with a 1:36 twist. (might be a tapered barrel - don't remember that particular detail off the top of my head).
In any event, it is a fine looking rifle - great example of a Shenandoah/Virginia Golden Age rifle, just a very fast twist for what most of us consider "normal or typical".
