If that's the case, then could this be part of a coin operated ride, or possibly a fairground ride? It has that 'look' about it.
Licenses, to my knowledge, were never granted for such things outside of Disney World so it could be unlicensed. Does it have any written information anywhere like copyright or date? It certainly looks 70's early 80's given the paint job.
I'll post some more photos tomorrow, with the dimensions. I was given it by a friend who was demolishing an old star wars shop on the isle of Wight. He told me it was from a pinball machine, but I'm not sure about that.
I've sent Vince our resident 3p0 expert an email link to the thread for you, with luck he will chime in soon & maybe shed a little light on this funkey item for you Andrew.
I seem to remember the Star Wars pinball machine having Darth Vader on top of the scoreboard.....they may have been other options but this doesn't look like a licensed item to me
