I also write here to find an answer to my question.
Because I'm in the process of model construction in Special Navy 1 / 72 U-boats in question, and I found myself at a standstill.
Looking at the instructions of Eduard specific set of photo-etch details, I realized that at one point says to delete a detail over the bow of the boat, see picture attached:
Looking at some documentation in my possession, I don't see that type of structure/support!!!
And here is the question!
Why Trumpeter, Special Navy and ICM had "created" this support / structure?? There goes or not??
Someone can take this big doubt??
Thank you very much for your help...
Mario.
