This is the Pre-TF version of Shockwave, before Takara obtained the rights to produce it as Shockwave from ToyCo. This is NOT the KO version sold by Radio Shack. It is the version that Radio Shack knocked off to make their KO. This is a genuine pre-TF item. Box has wear but displays well. Toy appears to be unplayed with. 

Please see my other auctions for rare Japanese G1 Transformers and AFA items.
