These were built by Flame Boy Products of East Berlin, Connecticut USA. Available in stainless or aluminum - one or two burner. They used Vulcan Sa-fuel - the same used in the Vulcan Safety Chef. This one is stainless and near new. Very well made and heavy. The drawer in front has to be unlocked to draw out and the fuel container cup can be removed. The lever on the side rotates a cover over the fuel to shut off. The burner area is very much like the Vulcan. There are tabs on the bottom near the feet that swing out so it can be secured. The grill locks or tabs can be turned so as to remove the grill or grate. Found some reference to these on line in Popular Science and Boating magazine's from the late '60's.
