Although very dirty on the outside, the inside of the fount, burner and vapouriser were very clean. Plus, the cleaning needle is not broken - BIG bonus ! The hood and frame were treated to a bath in citric acid before a gentle rub down with fine wire wool, the frame was then polished. After the fount had been cleaned out, it and the collar were washed with soap and water. The fount retains much of the clear lacquer which has helped to protect the brass, so I decided to keep as much as I could. Oxidised areas were gently cleaned with fine wire wool. The mica shade isn't perfect but it cleaned-up rather well. Notice the overlap at the join - originally made for a different lantern ? Or, bad measurement ? Nearly there. Up and running.
