3rd set of pics. I found one Happy days one, and another that is like the one I have (Not exactly the same-mine has legs) on eBay. I have the power cord end, and have the voltage stuff that I need, so I can make it light up again soon. Does anyone have any other info on these? Is it rare at all? Anyone else have one?
