In 1/700th, I believe you'll find some or all of these on the Leviathan set 'X': Parts #31 (3 each) and #33 (2 each), and; Skywave set E-5: Parts 17 & 18 (3 each) (I believe these latter may be submarine mounts, I don't recall).
I haven't updated my Skywave sets beyond E-2, -3, -5, -7 & -10, nevermind the 1/700th Nano Dread sets.
