Those are two nice fowlers, the old and the new. Any indication as to who made the original? Neither are too much like the VA piece that I have. It has a walnut stock and a cheekrest. Since it apparently shows reuse of a Scottish(?) barrel, the length is a little short, about 42 inches, as I recall. And nothing at all fancy about it. Only really good things about it besides the unusual barrel are the 'M. Sheetz' lock and a nice side plate.
Photos one day soon, I promise.
