I disagree that the outer torpedo doors look smashed, particularly in the photo from the port side (the stbd side pic is a little harder to tell, and MAY show some denting).
When you look at the photo of the port bow, the doors are inset at the forward end, but both doors are the exact same amount and it looks regular and machine made, not dented.
The forward end of both doors seems to be inset into a depression in the hull, but the depression is straight edged, square-cornered and regular. And there is a triangular shadow above the leading edge of both doors that seems about the same and looks like the casing overhangs the doors.
It looks to me like this is perhaps a variation on how the doors operate. Simon could probably set us straight on this, but I think most outer doors operated on a hydraulic piston that pulled the after edge of the dorrs into the middle of the casing, thus exposing the torpedo tube.
In this boat, it looks to me like instead of pulling the after edge of the door inward, a piston might have pushed the door forward along a sliding track into the depression forward of the door. The result would be that the rear of the door followed the track into the centre of the boat, again exposing the torpedo tube. Think of the way in which many sliding doors for mini-vans go along a track and then pop in at the last moment to seal the door shut.
As I said, it's harder to see on the stbd side (the picture on my computer is darker and I have no way to lighten it) but it's possible that the doors are dented on this side and/or that the doors are sliding instead of being hinged as described above.
