Hi arjay.
The Queen Mary 2 model by Revell is to be released at the end of the year in 1:400 scale.
I was involved with building the real ship on behalf of Carnival Corporate Shipbuilding at Chantiers l'Atlantique in Saint Nazaire, France.
I can help with details of the ship and info if you require.
All the best,
Beau.
(Can't beat building the real thing)
