One of eighty-six early incandescent lamps. Short
One of eighty-six early incandescent lamps. Short and filament, rather thick with curiously rough surfaces and rather bulky joints. No filament supports. Attached to platinium wires passing through long internal stem. Small spherical bulb with neck. Top pip. No base - platinium wires project about 2cm, bent back. Manufacturer unknown. Has "6 March 6th 1888" engraved in glass. No ratings. Shape suggests a san or woodhouse & Rawson lamp - but why the engraving?
