This is a vintage Pyromid Outdoor Cooking System. Its a collapsible stainless steel grill / fire pit for camping / backpacking. It has a lot of pieces, they all fold down flat and stack in the case. I did my best to assemble it for pics but it may not be 100 percent correct. All parts are present with the original box, carrying case and instructions. Additionally there is a 5 piece raised stand that fits the stove that may have been an option. Awesome find if you collect vintage camping gear or if you want something vintage and unique to use on the trail or at the campsite
