Thanks Dirk, I had seen that book in the internet both in german reprint (140$!!) and english translation from a US editor (9$!!), what a difference in prices! However I have seen a review of the english version that indicates that original pictures are no longer there, but instead internal shots of a Type VIIC boat. So I'm a bit in doubt wether to buy one book or the other...
Anyway now I know by you that what I'm looking for is inside it, so I will get either version ASAP

Many thanks
