I think Molly has a valid point. We, as builders and collectors are very passionate about our longrifle. But we are not the norm. The longrifle is also not truly appreciated for its art component, and that each piece is a one-of-a-kind work.
When you get into the mass produced guns, there are certain 'collectible' ones, ones with limited production, rare, or otherwise. Why doesn't the longrifle, which is even rarer by definition, have the same appeal to collectors on a broader basis?
