I am looking for someone that I can send a photo of a tube that was allegedly recovered two years ago near Camden Arkansas. It was apparently in the basement of a log house that was torn down a couple of years ago. It has metal wheels, but a wood carriage, which is mostly rotted away. Most of the metal fittings for the carriage are present and in the photo. The tube is interesting. I am not sure if it is rifled, but it is defiantly a muzzle loader. The tube is odd in that it almost appears to be double reinforced, similar to a Parrott rifle, but with a much longer reinforcement that extends past the trunnions, then decreases in size and extends for another foot or so before ending. Similar to a Wiard or a Blakely tube, but not exactly.

Shaped a lot like this gun, but I am guessing 6 or 12 pounder.
