Here is a used Coleman single mantle gas lantern model 242C and is dated 4-9 (Sept. 1944). The tank does not have any dents and there is some paint loss as seen in the photos. The top vent has chips in the enamel as seen in the photos. The glass globe has 2 chips on the bottom rim as seen in the photo. The straight line Coleman logo on the globe is very faint and will not photograph I have not lit this lantern. It pumps up and releases air when the valve is opened.
