An eBay auction offering brought this question to my mind.
An "Original Revolution II Quad Line Stunt Kite"
It is a rather unattractive solid blue color, and supposedly in good condition. It is not advertised as a collectible, but the asking price seems a bit high at 75% the cost of a new "improved" Rev II.
I have seen it too
It looks like one of the 1st RevII...
