Well, Matthias....., it's an interesting subject you're asking about.
I guess all members eyes and the spot lights are now turned in my direction, but let me just say it at once (so all of you don't have to waste valuable time waiting) I don't think I can help you here. Sorry!
You know, these trawlers were built long before my interest in the subject, and all I know about the trawlers is what I myself have in the Sterkoder Yardnumber-list, and in general how the contract was given to Sterkoder Ship Yard as described in the Sterkoder 75th Anniversary Book.
No special stories and no drawings though, but as usual in these kind of cases, I'll bring your quest with me in the back of my head....
Now, the interesting part would be if anyone else out there can help you, and come up with stories or things we don't know.
