This lamp has always been in our barn in Norfolk. Was certainly used by my grandfather until 1944. Likely bought locally in Norwich, or possibly London. The shade may or may not be associated with it. I seem to remember a pump lying around but regrettably that's now lost. No markings anywhere apart from patent dates as shown in picture. What have I got here? If it is a Kildark that would figure quite nicely as the old man was always "careful" and not spend money on brands! Seems complete and in good nick other than some rotten wick in the curly vaporiser tube and oxidation of the steel parts. No signs, to my eyes, of any repairs. The nickel plating is battleship grade! I'd like to get it going but perhaps you guys can give me some pointers first. My main collection is old whale oil and wick lamps so this is something of a departure. We've puzzled about this lamp for years.
