I found this on Amazon, though WHSmiths also sell them. The original series USS Enterprise, it comes prepainted with all markings applied. its a lovely well detailed kit for its size. On top of all the saucer section lights up.
The Running Press Enterprise alongside the Futura refit Enterprise. I should point out that this kit costs £5.59 from Amazon.co.uk, though some crafty buggers are trying to sell them on ebay as an exclusive from the Eaglemoss Star Trek magazine, with prices upwards of £20!
