Being the mathematical genius that I'm NOT, I couldn't detect any irregularities with the hull sections (but that don't mean much!!). I've just completed planking the hull and here's a look at her sitting next to one of my Revel Type VIIs, U324. It is really hard to believe that these subs are of the same scale!!!!
It is no wonder that the Seiren flight crews were "........surprised at the overall size of the submarine......".
Now the filling, sanding, filling, sanding, filling, sanding, etc, etc. you get the picture.....
