The only reservation I have at the moment is that you've used the 6in Mk XXII triple turrets (for some reason these were also used on the G3 profile Darth did). The XXI twin would most likely be the one used, the same as the 6in twin armed cruisers of the period. Other than that I would say this has been long overdue. Good work.
I guess Darth reasoned like I did: The Mk. XXII was mounted on the Nelsons(according to Navweaps), so it made sence that the G3/N3 would mount them too. I've made the turret, and especially the barbette a bit smaller, so that it fits more for a twin turret.
And thanks. Becouse of the similarities between the G3 and N3 I'm using and modding some of Darth Panda's bits, like the conning tower, so I might be able to make an update tonight.
