lets take it step by step....first of all i can see a paraffin lamp. i.e. little tank with a wick ..then there,s the compartment with a vent,that looks like it would hold the heat source,most likely fossil fuel,the little container above and to the side looks like a water tank, which is attached to a bigger tank on the top....the containers below with the shelves are for holding..food, or whatever.....
