I just located a army field oven from 1944. Pics look like it may make a fine vertical smoker if I can ever get the guy to return my call. Has anyone had any experience with these? I saw one at a cookoff a year ago and have been keeping my eyes open. Says it is stainless. Looks like may have a insulation layer fro the side panel. Only pic available so not sure which is why I am trying to contact this guy.
