Fiberglass desk lamp restoration and ID  

Hello, Bought this nice little desk lamp this weekend for really cheap, sadly it's not in the best condition (no chips or cracks on the shade though) There is some discoloration on the shade which I assume came from previous use with too hot of a bulb, But the discoloration is only on the outside, not the inside, which is a bit weird for a burn. I doubt it's possible, but any way I can get this back it's original colour?
I've also scoured google images with a fine tooth comb trying to find another but no luck, any of you recognize this lamp/shade? (excuse the clutter in the pictures, In the middle of packing for a move.
