I'd like to get some info about gun grease and oil used in the 1840 to 1860ies. I do not think there was much petroleum based stuff around at that time. I've been doing some tests with making my own none petroleum based oil from mutton lard, beeswax and vegetable oil, something that is fluid and can be used for preserving the guns from rust. I can get a fluid by using canola oil (also good for sealing a skillet). Treated the old Manhattan a week ago and shot it today. Surfaces looked good and felt smooth but not sticky. Cleaning the gun after shooting, with hot water and soft soap, was easy, So now, if the concoction will stay odourless for a longer period, I might start using this as my standard choice.
