Need help with 3D IJN Yamato Turret Mechanism

[renogaza]

can someone help me acquire accurate and extremely detailed information
about the firing, loading, feedback and aiming mechanisms of the yamato's
guns?

i need to build a 90~100% accurate 3D cad/skp model of the yamato's
18.1in guns as an addition to my current project, i will accept any format.

i need info on how the barrel retracts from recoil, full barrel length, the
shock absorbers and hydraulics, the sealing method of the gun breach,
the gun breach door mechanism, breach door thickness, the bore length,
the bore type, fulcrum location, armor thickness, shell length to diameter,
size of cordite/"gun bag", no. of crew per turret, aiming mechanism,
aiming booth, fire control system, powerplant, shell delivery, cordite
delivery and lastly, turret exits

thank you for any and all the information you can offer
