Hello everyone, I want to convert 1/72 SN model type IIA to type IIB, especially U-7 or U-9. I have some photos on U-7 deck, but they do not cover entire deck. I'm trying to put together a scheme for the whole deck. I assume that all boat of type IIB hadn't same deck layout, becuase pictures on the board near the front of the tower U-9 and U-7 shown slightly different layout (some missing holes). I need photo on deck behind steel plating on bow and stern and length of this steel sections. What is the width and length of one hole in the deck and width of the plank of which the deck is made? And I'm looking for some deck scheme of some existing for the type IIB and also C and D.

Thank you in advance for any assistance.
