Welcome to the forum , CovKY11 .
It might be possible that your item is more vintage than 1970's ....(the exposed wiring looks 70's era , though)
the scroll-work looks nice .
I'd check the lamp over with a magnet , to see if your item is brass , or brass-plated steel .
Although I can't tell 'beans' about your item from the images , but , it's possible that someone converted this unit from a kerosene triple-lantern set to an electrical one .
There may be makers' marks/hallmarks under the brass element(s) where it was secured/hung from above ... you could dis-assemble this section of the lamp to take a look-see .
