G’day all, here is my recently purchased Coleman CQ lamp and i think it is pretty much original. I believe it is from the period 1919 – 1924. If I’m wrong in any of this please correct me. There is no date stamp on the Font. The burner air tube is stamped _ U.S. Pat. May 13 1919 _ British Patent 153329 The mixing chamber is the pre 1926 version. (no raised flats on top) The collar is plated brass. (not steel). The valve wheel is bonded fibre. Marked CLOSE >>>> B The handle is Bakelite and although it is too worn to read in the photo it is marked: COLEMAN – QuickLite _ WICHITA KANSAS. USA _ 1017715 Non original parts. The generator would have been a Q type NOT THE R55. The steel washer under the handle securing nut wasn’t there originally. But due to the brittle nature of the handle I put it there to protect the Bakelite. There was no shade or globe with the lamp and I don’t have one. Fettling of this lamp is here.
