Weird looking Monopod Support

Not quite sure what this guy is, but I found it while doing my daily cruises on eBay. It looks like it's on an estate auction which means it's something that isn't made any longer. It's a camera support system that folds up and is adjustable through a weird telescoping method. Pretty cool, but I wouldn't pay that auction price. Check out the auction here (unless it's already expired by the time you read this).
