Nintendo 64 N64 Foxdata Chrome Leopard Controller
This controller is one of four different patterns created and sold in very limited numbers by a company called Foxdata who were based in the United Kingdom and advertised the controllers for sale in early issues of N64 Magazine.
It is not known how many Foxdata controllers were sold. It's believed to be less than 500. Whatever the number it's one of the best looking and most interesting collectable Nintendo 64 items around.
