All the parts are just awesome. ( All made of brass, copper with a Nickel coating. ) Up untill WWII, Colemans were made of these parts. After the war, Coleman started using plain steel in their tanks and burners. This 1924 Quicklite was taken apart and boil in water with lemon juice at about 4 ozs juice per gallon of water and cooked for 20 minutes. Amazing how 84 years of grime is boiled away!!! This lantern should last another 80 years. ( Too back lanterns today aren't made like this!!! )
