Allright, I have both hulls glued together, figured how to mount the model on the custom stand and have been doing some more research on painting the boat. Unfortunately here I ran into a small glitch: I may have made a mistake while creating the mock-up of the paint scheme.
I would really appreciate your take on this.
Looking very closely on the original picture (in the starting post of this thread) I have found out that some of the lines are way too straight to be just wear on the paint (highlighted in yellow here):
Doing further research I have found out that there was actually a color scheme including a combination of yellow and black stripes on the school boats. Here is Revell's paint scheme of U-2514
and picture of the real U-2514:
So I figured that the revised mock-up should look more likely like this:
Another two facts supporting this theory are that the little symbol next to number 2536 is Frontreif badge (painted on the school boats when they were ready to leave the school for combat) and U-2536 never went on a single patrol. It was part of the 31. Flottille (training) under the command of Oblt. Ulrich V
