This GI stove was purchased in an Army-Navy surplus store for 99.95. It weights about 50 lbs and disassembles into three pieces. It has a heavy iron grate to allow the ashes to fall into the bottom section for easy cleaning. The flue here is 4" diameter vent pipe. Wood is fed from the top through the removable round lid pictured. Of course it is recomended to have some firewood stored away.
