Thanks all for the nice comments. I was surprised at the size... it was bigger than I thought from the outside. I is sometimes difficult to get a true perspective even when looking at pictures and film.
It is great that she is completely out of the water and the whole boat visible.
@kylania hehe erhmm that is me, I am average hight 5,8 feet
@reaper 7, I didn't see the TDC

unless I am blind, but it could have been removed by the Norwegian navy who operated the boat for a while after WW2 and was never replaced. I will look into that.
@mswyx ues the torpedoe tubes were sealed unfortunataly. For the most part she is a pure WW2 relic, with inevitable repairs and modifications that probably were deemed minor or to expsensive to reintroduce.
