Seeadler has replied. He says that he did not add any extra models. He replaced an existing model with his model of Konig by converting it to the DirectX format.
Basically this is what I've done here. I converted Seeadler's Konig to 3DS and made a crude retexture using UVMapper. This was imported into Deep Exploration and exported as a DirectX format model. I renamed this as Scharnhorst_voll and overwrote the existing Scharnhorst_voll file. I also added the texture plate to the textures folder.
I'm not very familiar with 3DMax so I tend to work out of Sketchup and export as 3DS. Uvmapper is a quick wysiwyg way of texturing that I prefer.
I'm sure it's only a short step to creating a new model file and adding an entry to a catalogue somewhere.
