Steve,
If you still need help with the pictures, feel free to message me and I'll try to convert them to a manageable size for you.
I want to touch on something Mr. Briggs said, which was an excellent point I forgot... the amount of items at museums that actually do not go on display. The majority of the items they have in their "safes", "vaults", and or "basements" will probably never be seen and if for some reason the curator changes, like mentioned above, and the political atmosphere has been galvanized so much around a particular subject, it might be shelved, indefinitely.
In case you didn't know Steve, because I didn't at some point in my life. Dr. John Murphy, who I never met, wrote, what I would consider, the best reference books containing Confederate firearms. I think I own all of them, and they are incredible, in my opinion. I believe Mr. Briggs is speaking of the same man.
Mr. Briggs, who I have had the pleasure of meeting several years ago, is one of the most knowledgable men on the subject of North Carolina long rifles, and has contributed a great deal to the preservation of the knowledge surrounding them. Everything he said regarding museum's is true, and he has the experience to give such a warning. Please take note, as I think you have.
Regards,
Bob
