I found this: http://www.ebay.com/itm/NINTENDO-64-...ht_3803wt_1396
Now it says Glover, but notice the "2" scribbled over. The seller mentioned nothing about it. Obviously it makes one believe it is another Glover 2 proto. Who knows. On the back it says "Early Build".
Time left is five days. I don't collect prototypes but I support their legacy. Hopefully this one will go to someone who is willing to at least show a little footage.
