Hi Steen,
If you get the latest ( May-June) AFV modeler magazine theres an articule in there showing the 1:16 Kingtiger model with internals and also a Kingtiger that they are restoring in Switzeland . This is I think part two of the articule so you may need to get the previous issue.
All the best Littletankman
