A great and a lot of work, done by you on the one hand and Zoli / csatahajos on the other hand. Very interesting to study. I even didn't know that there were more design variants as Siegfried Breyer mentioned in his book. For example Breyer doesn't mention the pre-official design variants in his book. I think he had not access to some sources back then which are now available resp. they were not known in the West.
Further, I would like to show you a suggestion for a 51-cm-triple turret. As I saw your turrets, immediately a thought came into my mind to change the appearance a little bit. I personally tend to keep the inner edges of a turret more "smooth", but one can endless discuss about. "As one likes it". The turret is not 100% finished. As I said: Just a suggestion, a thought.....
