Dear Andreas86, you deserve all the Kudos you can get. What you have done is just outstanding. I have loved and played this game since it's been out in the 90s, and your mod lifts enjoyment of it to a whole new level. It's like the difference between the submersible torpedo boat and the electro boat.
Regards the type II control room, I was wondering if the Vesikko as the type II prototype might be of any help? There are a few pictures available on the net.
