Model 817. Also marked F82. Top quality German manufacture. All four wall lights are in the same vintage condition (small scratches). For 4 bulbs type E27. Each of them has 3 brass tubes with a brass piece at the end which is screwed in. They probably served to hold a piece of glass each, but we haven't been able to find a photo of them in a catalogue or similar. All pieces are signed. The back parts are made of metal. They are fixed to the wall with some round shape aluminium pieces (provided). European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
