First of all, I apologize if I'm not supposed to resurrect long-buried posts. Not sure what the rules are on that.
Anyway, I've taken an interest in the Appalachian "Bear Pistols" that pop up on this forum from time to time, and I've been poking around the web to see what's out there. The most productive "hits" resulting from the searches have led directly back to this forum. However, I did find this, which may be of some interest:
National Plott Hound Association News. As near as I can determine, this newsletter dates to October, 2010. It has a couple of pretty good B&W photos of Mont Plott's famous pistol and its holster, as well as additional photos of accoutrements, some southern rifles, and a few other firearms. The text is interesting. While it does not provide the specific detail folks like us want to see regarding the guns, it is well written. There are some nice pictures of Plott puppies, too. I don't own a Plott hound, but I'll admit to being a fool for dogs in general.
Best regards,
Notchy Bob
