Did you bother to translate the German to English, it clearly said that the TIGER I will be done by Trumpeter /WSN and you can see the remote for the tank in the picture while Matorro had done the King Tiger which you see the Strumtiger behind it with other products..

let me translate for everybody here:
The tiger succeeded really well, how one could expect it evenly from Trumpeter. An early middle execution with early castors and late dome, as well as spare chain mounting plate at the tower and individual headlight are represented. The tank is equipped with a tubing retreat and firing lightning like the T34, only negative point is probably the same technical equipment as with the T34, speaks the same "approves of" control and transmission still is however possibly changed.

which this part shows the King Tiger
And here then the new Matorro model: The king tiger
more pictures of the KT

Unfortunately also these pictures are not so tingling become however I can say that the tank with Zimmerit represented are. Brings closer data and improves pictures gives it then after the fair. After the fair I can report also new over the Sd.Kfz. 222/223 - kit to you, since in time to the fair one arrived. To this way first times.

So it clearly says Matorro is the maker of the KT
