I can not see any of the pictures you posted. My advice would be to take down the anything that looks like a model number and stick that into google. Find out what they are exactly and what they look like brand new. Find out what the retail cost would be and search on ebay to find similar listings. Then you can determine if you wan them or not, or if you want to sell them or not.
Maybe if you stick attach a picture, I would be able to tell you more, but I can't see what you're talking about. Sorry.
