I think we're getting a bit off the topic of J.P. Becks, but this is a subject that comes up often enough on the ALR and I'm sure in other forums as well. As one of the younger folk in this field (I've still got 6 months left in my 20's!), I can see somewhat where my generation is coming from. I don't want to speculate too much why younger generations may not be as interested in these historic pieces - I'd end up writing two or three pages worth if I did, so I'll save that for a new topic.
I wanted to own a longrifle or musket since I was about 7 or 8 years old and read a book in which the main character (a drummer boy in the Massachusetts militia) describes his dad's musket as being 6ft tall. I asked my dad how tall 6 feet was, and I can imagine the look on my face when he held his hand 3 feet above my head. That interest never died, even though it was another 10 years before I built my first rifle. I don't know what exactly sparked my interest, but it's something that I try to pass on to others my age and younger, especially the appreciation for these pieces as functional works of art, as tools that were decorated and cherished by their owners, that played an important role in the early days of our country. Even at the very liberal college I attended, peoples eyes would light up as I described these not as cold metal "guns" but as something far greater - that is, until they realized what they cost.
Like Dick says, there are still treasures out there to be found if one digs long enough. The best piece in my collection was a mislabeled pile of 6 different chunks of wood at a gun auction. It's something that probably has a 500% increase in value. The rest don't have as much value, and most of my favorite pieces are actually European guns. I don't spend money on run of the mill pieces that have had so much restoration done to be barely recognizable as the original piece it once was. I'd rather spend $2000 on a fine original English or French fowler in good condition than a poorly restored longrifle with no discernible history or provenance. What that ultimately means is that most Pennsylvania rifles that I'd be interested in owning are beyond my price range for the time being. That is, until I find another piece of treasure tucked away in a dusty corner.
