"Sound" research for my scale Bismarck

[FightingSteel1]

Hi,

I thought this might be a good place to ask a couple of "sound" questions about the KMS Bismarck. I'm working on a functioning model of the battleship right now, and I've acquired some parts to make a sound module for the vessel.

I was going to definitely model the sounds of the 15" guns, and possibly a mix of the secondary armament/AA guns. Beyond that, I'm not sure what other scale sounds the ship would make.

I thought about engine sounds, but I doubt you could actually hear that. I saw something from a crewmember of the ship that said he couldn't even hear the engines from his post a couple of decks away.

So, anything else I could model? Would it make any sense to model a fog horn or bell sound? Did the Kriegsmarine use an audible "general quarters" alarm or anything that could be heard from a scale distance away, or should I just stick to gun sounds?
