All you have to do is show us anything that illustrates the figure. For instance, a carded figure, a file card, an insert pamphlet, anything that shows this figure. It is an 1983 Flash body. Hasbro Made in Hong Kong is written on the butt. No other markings.
Body is gray plastic and appears to be factory painted.
Backpack is all white. Purchased from Whiz Bang Toys in Florida. It is defiantly not a Brazil figure because it does not have the words Estrela stamped on the back. Whiz Bang's Mike Herz purchased it from a G.I. Joe designer. Mike checked with his source and conclude that it is most likely a prototype.
