I have a 1919/1920 QL and have some questions: 1) The lantern is green but appears to be brass underneath. Did Coleman paint these at that time or could it just be that tarnished? 2) The lantern does not have a globe but instead has a solid metal shaped "can" instead of a globe and has a sliding piece of tin that covers the hole to light the lantern. Since metal can appears to be factory made with rolled edges on all sides and even a rolled edge on the hole to light it, I'm wondering if Coleman ever sold this model as a heater instead of a lantern? NOTE: The lantern also has a wire hanging hook fastened to the carrying handle that appears to be factory made/installed. Any advice is appreciated! Attached are some photos including the shield (in lieu of a globe), the sliding cover, and a photo showing the hanging hook on the bale. Do you think this lantern is a rare model? There are no dents and since the top and bottom are brass, I would think it could be cleaned and polished to look something like this one.
