The sight of him alone is enough to tell you who he is. He's the 1st and the ORIGINAL AstroMech in the universe. He even predates that little blue and white astromech in that galaxy far, far away He's been made down to 1/87 scale.
Just imagine having this guy on your HO scale train layout. People will figure you must know someone real important to get a visit from this guy. Your layout's news media will be all over him. Because he rarely goes out in public anymore. He's that big of a movie star.
Which because he passes the tests for FUD material. Makes him the absolute world's smallest scale he's ever been created in. His dome has been left off, so that you can paint the details in his head. And in hopes of polishing the dome enough to maybe see those painted details, if just barely. All you have to do, is cut it off, detail his head, polish the dome and assemble.
Just becareful not to use a glue that would cause the dome to frost over. A rubber compound or a wood glue might do better.
He scales out to be 7 foot 2.5 inches tall in 1/87 scale. Which makes him more correct for HO scale.
