Ok, I know nothing about this lamp. It came from an estate sale about a year ago and I have yet to run any oil through it. It is rather unusual.....instead of having a gold goddess it has The Madonna...so I thought that it was pretty wacky / creepy. The light works when it is plugged in, and you can hear the pump running too. As I said I have not put any oil in it, so I can't SWEAR that it works, but the pump does SOUND to be functional. This lamp is a table-top one, the cord comes from the back and there is no chain on the top and it stands abt 18 inches tall. It is in the same condition that I bought it in (read--needs a good cleaning.) Since I have not had time to do anything with it, I am trying to sell it for what I paid: $15. Shipping in the US should be abt $13....if it is any more than that I'll pay it. If you want it let me know!
