whats the deal with this?

.so last week i won this on ebay. i thought a cloudy yellow/orange us gen1 coachlite. turns out its a greenish color with yellow wax. it has a weird metal lid and the coach top does not fit over it all the way to line up with the holes in the rods. the cord is white with a push button swich. what the heck do i have here? and how do i get this lid off so i can work on it?
