Hello Andreas,
Thanks for your message. When the photos were on sale I took copies, though they aren't great quality. Despite the quality they are interesting photos and I think you'll like them. If you send me a PM with your email address then I'll email the U 994 photos to you.
U 994 was launched with a Turm II tower (one 20mm on the upper platform, plus one 20mm on the lower platform). In 1944 a Turm IV tower was in place (two twin 20mms on the upper platform, plus one 37mm on the lower platform).
Cheers,
Dougie
