The Energon Pub

i found a grey shockwave. i know there a radioshack version in the 1980's.this one is in the box complete new and a old vintage.die casting the name say ROBOT PISTOL MADE IN TAIWAN. does anyone know information about this vintage grey shockwave.has the same lights and same sounds. how much is it worth to buy in the box with instructions and looks new.the person collects like old late 1970's toys and other vintage stuff. any advise before i buy him?thanks

That's probably a Knockoff. A grey version of Shockwave was indeed sold at Radio Shack, but he was sold under the name "Galactic Man", and had a minor difference in tooling: the trigger didn't have the rectangular plate, so it looks rather... phallic
