I recently was asked by a friend to clean up an Camel Gun from Afghanistan that he received from his father quite some time ago. I thought that I would carefully take it apart if possible and clean it up a bit and try to find out a little bit more about it. I have attached a couple pics. Has anyone seen anything like this or have any recommendations on how to clean it up? I have a muzzleloader and am familiar with how to clean blackpowder etc, but I have no experience with something like this. I am more interested in just cleaning it up and preserving it the best I can.
