I lucked into an original Oklahoma Joe's offset cooker this past weekend and have been doing a little research since then. Does anyone know if the company branded its products with model names in the early days, or were they marketed basically by style and size? I'd love to look at an old catalogue or promo material to match my model, but I can't find anything of the like. A couple pictures are attached for visual reference. I'd appreciate any tips from experienced eyes out there.
