Queen Anne #0 burner Lomax finger lamp & Ehrich & Graetz of Berlin "Matador" Brenner (burner in German) Both are from 18951905 timeframe. On the finger lamp, the Lomax dripproof font was patented in 1870. There is a raised collar to contain oil spillage when filling the lamp. This design was licensed to several lamp makers of the day. The Queen Anne series burners where designed in the USA around 1880's and manufactured by a number of brass fabrication companies. This one was made by Scovill. The E & G brenner was cleaned and serviced by me in a previous YT video. It is now mounted on a large #3 size glass font with the collar changed to a European size of 1.5" which excepts the E & G burners 15''' & 20''' along with other Euro burners such as the Kosmos Brenner 14'''. The Opalescent shade is from the Victorian time period, about 1890's early 1900's. It is from a hanging hallway lamp but the 4" fitter fits the 4" shade ring perfectly and looks good so I used it.
