While hunting I actually eyeballed this find. It was nasty and very dirty and after 3 days of cleaning and soaking in hot water with dishwashing liquid it looked alot better. Never have seen one of these and thought I'd post it to let you guys look at it. It had what looked like pieces of tabacco stuck on the inside. The top spins around and I think the pointed jagged spears on the inside tear the tobacco apart but not sure. The botton unscrews off and holds the shredded material, atleast, that's what I think it does. Thanks for looking. There are no markings but it is heavy and the metal will not stick to a magnet so I'm thinking stainless steel?
