Some more detail:
105mm inner gun for practice firing with 15� main guns:
Ever wondered what is the purpose of these cannisters? Several comments seem to suggest they are for storing cleaning rods for the main (15�) guns. Well � they are not!
Each such cannister contain a 105mm practice gun that was used for live firing practice with the main guns. I have seen such a gun myself: Not in a cannister, but inside the gun housing og the 15� gun housing in M�vig, Kristiansand in Norway. The 15� inch gun in M�vig is a gun museum, complete with a Bismarck/Tirpitz gun, bunker etc, etc. I must see if visiting to Norway!
So, what about the cannisters? Well, take a look at the picture from Tirpitz after an aerial attack: The picture shows the barbette of gun Bruno. A bomb hit has blown the cannister open, and beside it � the inner gun! The larger, huge section at the end og the tube has a broad ring around it. This is the liner that centres the 105mm inside the main gun.
Such inner guns in quote common. I have used it myself in 14mm calibre inside a 155 mm M109A3G-howitzer to practice direct firing.
Lanterns:
Picture is showing some of the lanterns hoisted and used for signalling. Also notice the flag signalling platform.
Bismarck bars are simply an arrangement for mounting lanterns in patterns for signalling at night. If you study pictures of Tirpitz, you will not find these bars, but instead an (seemingly) electric arrangement to fulfil the same purpose.
