I noticed that, too. :| The paintjob looks a little weather-worn. The videos were posted on Youtube within a day or two of them having been filmed.
The guy who built the model also has a smaller model of the Queen Mary, a model of the Mauretania 2, and another of the Queen Elizabeth. They're all really, really nice. He said he was working on a battleship and I think a Cap Arcona was in the works, too.
