I recently saw one... [Emma C Berry from Model shipways/Expo] ...listed on EvilBay. The listing stated the condition as New, but the photos of the box looked as though it had been stored in the bilge of the Victory during the battle of Trafalgar.
That's where I found mine. EBay, not Trafalgar. It cost £83 which was a bargain. Right place, right time I guess. You just have to be patient.
