Alan Carter (Nick Tate)
The Mego Alan Carter figure is the most unique in the line, eventhough he was pictured in the Palitoy catalogue as wearing a moonbase uniform Mego decided to put him in an ersatz version of his space suit (he was a pilot)but his helmet is all wrong and shouldn't his hands be white? Still the toughest doll in the line and a fine likeness.
The original Alan Carter prototype featured in the 1976 Palitoy Catalog showed him in his Moonbase Alpha unfirom. One might venture a guess that Palitoy decided it looked too generic to have three of their characters in white
Actor Nick Tate continues to pop up in movies and TV usually as a crusty "Crocodile Dundee" type. He has appeared on Star Trek:TNG and many TV commercials. Ironically, the original pilot for Space:1999 had Carter being killed but Tate proved so likeable that they kept him on.
