I think that wartime raid film shows this Tallboy making a splash in water, as there is a splash that is a lot smaller than the other Tallboys that clearly explode, and its a big enough splash to be a 12000lb Tallboy hitting the water and not going off.....and if you freeze frame both films and screen shot it, it does look very close to being the same one.....but I'm not an expert.
The ship would have been in front of the saw tooth dock structure that has been built since, but the jetty coming down from the two U-Boat pens on the opposite site appears to be roughly the same still.
