Hello again!
Thanks everyone! Now - out of chronological order - the third unit of the class, the Imperator Aleksandr III. She was mostly identical to Mariya, but did not receive the crane-like application at the bows (either some kind of mooring aid device or some kind of minesweeping gear, or both, sources differ); at least there are no photographs showing her with it. She received some kind of bowsprit instead which was not hinged, but retractable; what purose it served (probably the same) I could not find out. Maybe Golly knows more about that. The other differences were the brigde (no charthouse on top of the bridge, because she was not fitted as flagship), the slightly different antenna rig, different placement of AA guns (two abreast on turrets A and Y) and the lack of the foremost 130/55 gun (Mariya's forward casemate tended to be flooded all the time when she went at speed, so they removed the gun and welded the casemate shut on Aleksandr). Aleksandr III had also received additional rangefinders at the rear of each heavy turret, which Mariya would have received too if she had not been lost early.
Imperatritsa Ekaterina Velikaya will follow next week, and the never finished Imperator Nikolay I later this month.
Greetings
