Late 20th Century Lamp . Juno?
The unusual shade is known as a pulpit shade, designed to direct light The lamp would seem to be around c1900 – 1910 . I think it is earlier because of patent date? It is very roughly cut on the shade, to allow for glass flute, it seems to be a proto type?
It has 'Crystal light' patent April 26 1870. Can't seem to find anything on this patent . It doesn’t seem to have any other markings except what is on the little wick turner.
There is another engraving on the back plate that is riveted on pulpit shade it reads
Patent JUNE 29 75 JULY 14 85 I am assuming it is 1885, as it ties in with patent date on wick turner
