Sorry, I can't see the photos.

I cut and pasted the images into the address pane and looked. Op, it helps if you will offload a couple of the pictures onto your PC and use the photo tool available on the forum or the code to insert them right into your post. Many people won't take the time to go to this effort to see your pictures, if you won't go to the trouble to do it yourself. It would also help if you include a picture of the entire lamp, including the socket/the harp/the switch. If they are original, it helps in dating. It's a decent lamp, imported from Italy as the writing on the bottom suggests. The wiring is modern and unless there is a maker's mark on it, it's impossible to use that as a clue as to era. It looks modern to me, last half of 20th c anyway, and without the other pictoral details it's only a guess.
