Yes nice pics, I have them and also a few very interesting more -I never saw them elsewhere- in this book I brought from my trip to Austria some years ago:
http://www.amazon.de/Deutsche-U-Boot.../dp/3813207617
I can only recommend the book, it's well written (Albeit only in german as far as I know) covers a unusual and poorly know stuff, and ships many interesting and never before published pictures
