I have never tried seeing if the wiring works. However, please keep in mind that it may or may not need to be rewired if you plan to use it. The Lamp is in amazing antique condition, little to no fading that I can see. The brass is tarnished, this can come off with polish.
I have no doubt that it can be cleaned like new if that is the desired look you want to achieve. Comes with the original glass prisms and whatever you view in the picture. I also have a separate listing for a Victorian Bubble Cranberry Glass Oil Parlor Lamp. If you are interested in both lamps I can give a better price.
