Extremely Rare VS 803

This could be from early 1960's or even very late 1950's. These lanterns are so rare that I know just about three (3) of them installed. There could be a few tens of them in the whole country (and possibly some in neighbouring countries). They exist in collections of course.

Look at the intact glass! The lamps are positioned vertically in that long opaque "skirt" so a lot of light is emitted to sides/forward. This was probably because of light evenness requirements under and between streetlights. Following models already had lamps in horizontal positions though.
