I got the Slave-1 ship for the X-Wing Miniatures Game. This belongs to Boba Fett the bounty hunter.
It is one of the large ships in the game and seems much too big to me. I think it is because I always thought the window was about the size of a car windscreen and it would be Fett’s head and shoulders behind it.
If I had paid more attention during the second film, I would have remembered seeing Fett float the frozen Han Solo up a ramp at the back which showed the scale properly.
These miniatures are supposedly 270th scale based on original models and designs from the films, so it really must be this large compared to the X-Wings, etc.
