Azzolin Brothers Capodimonte Lamp

My grandmother bought these lamps originally in the 1960's I believe. They are marked on the bottom with Made in Italy F-667 and F/666 Not 100% sure but I think they are Azzolin Bothers lamps. They do have silk lamp shades on them that cost $600/ea at the time. I am hoping to find more information on these lamps as well as the value. Please see the pictures for more detail.
