There is a serie called "Vom Original zum Modell" that covers all U-boattypes and from some types there are even scematics in A1 size from the same publishers. I don't know if they are still in print or even available but I have several of them and they are great, lot of interieur pics, technical info and of course scematics. There is a book of the type II too. The only possible drawback might be that they are only published in German.
