I can see it both ways, to some extent. If you just like to look at historical arms, study them for artistry and aesthetics and appreciate them as antiques, but are not concerned with the historical fine details other than they are are early American artifacts and tied in to the history of our country, I can see not being too concerned with the nit-picking that some of us obsess over. That's not a negative, btw: a rifle such as the John Rupp-signed rifle under discussion can stand on it's own regardless of maker or date of manufacture. Speaking for myself, conversely, I am interested not only in the arms themselves but also the men who were working in my own trade, and I am researching them not only as historical arms but also as representations of the men that made them. Viewed through this lens, it is very important to me to at least try to get the details right. None of us are perfect and new information manifests all the time, but I believe it something of a solemn task to ensure that I'm not making gross errors or blatantly misrepresenting something. I think this is why this particular situation is so offensive: people who should know better, and who - with even a small effort at original research - should be more willing to embrace a scholarly approach as representatives of various esteemed organizations, do not seem to be doing so.
