Hello Martyn,
And there was me thinking that I was the one that was always looking for odd reference material.
I have had a quick look this morning while waiting for my hot cross buns to become hot and so far all I have found is a photo showing what is reported to be some poor sould washing up in the galley.
This is on page 61 of the book"U-Boote" by Jean -Philippe Dallies - Labourdette.
I will keep looking as I am sure I have seen more some where.
I will state that if any group of people can and will help you its this crew here on this web site.
Good hunting

Hang on here is another photo , it`s on page 89 of the booy "U-Boat century" by Jak Mallmann Showell, ok it shows the galley, well part of from a Type IX.
Here we go, try this link, it should take you to a photo of the galley in U995, even got a cooker hood, well I think thats what it is..
