Thanks for the link!
There is a model of the Admiral Hipper in the Imperial War Museum, London which is either 1/50 or 1/48 scale. I wonder if this is the one mentioned in the article? Apparently it ended up in the National Maritime Museum, but most of their ship model collection is in storage anyway so it's possible they've loaned the model to the IWM.
I took some photos of this model at the museum during my visit there a few months ago, but they turned out too dark to be of any use due to the low light levels in the gallery.
