Since Magic1111 @ the german marinesims forum suggested to add the rotation of the exterior periscopes I tried to realize this good idea
and had a conversation with Ahnenerbe @ subsim forum via pm that he also tried this. After some endless hours of trying and days of testing
I finally realized to add the rotating periscope which is now turning to the appropriate heading of the optics, just like the UZO.
Have a look:
Now I only have to add the new periscope 21 times to 12 conning towers :)
