[quote="drasticplastic]Are you not thinking of the armored covers on the torpedo launchers? They had a roll-up canvas cover over the rear end.[/quote]
Nope...
I apologize if the pics aren't very good quality. I'm downstairs and my scanner is upstairs, and I don't feel like dragging it down. So I took these pics with my iPhone.
Pictures are from
Pocket Battleships of the Deutschland Class by Gerhard Koop and Klaus-Peter Schmolke.
The first pic is an undated photo of Deutschland/Lutzow, pre war:

Rolled canvas, no doors.
The second pic is Deutschland/Lutzow in '45:

The doors are clearly present now.
This last pic is Graf Spee in '38. No doors. You can't really see any canvas, either, but there clearly aren't any doors.

That's why I think they were added just prior to the war....
