Never have I ever… Seen a piece quite like this. Hand-made portable heater or stove – you be the judge. Pierced tin, with 1856 on the door. Inside is a small well-worn cup, presumably to contain hot coals. Authentic wear, worn thru and flaking in areas. Size: 5 1/2″ talll, plus handle, 8″ across, (see photo with soda can for scale).
