Thank you for the kind words gentlemen. Appears as if I being a newcomer to the group made a mistake by adding this lamp which is a C fount Q lamp in with my other Q lamp in the reference. I was made aware that the reference is for one model of lamp at once... I am learning slowly so bare with me Here are some more photos that go with this lamp. The mixing chamber, filler cap, & flat filler bung are specific to this particular Q lamp as it predates the popular CQ. The rounded valve wheel, weldless shade holder, and no patent stamp air tube would be used for another couple years on the new CQ lamps that would become one of Colemans most popular lamps of the coming 20's. A big thanks to Larry @coleman54 as he has taught me the majority of what I know on the early models of Coleman. This one being no exception thanks again Larry
