That would be the new Trumpeter Yorktown and the new PitRoad Musashi. If someone told me the Musashi has 1000 parts to the kit--in the biggest box I've ever seen put out by PitRoad in their 1/700th series--I'd be very inclined to believe them. How fitting on both counts. You get at least two complete sets of main, secondary and tertiary batteries. The Type 22 radars did look a bit out of whack to me but could be easily cut down. You get only--figure this one out--1 Jake and 1 Pete. Except for rails you may not need PE for this kit, take a look at the lattices...
While I've only started looking it appears that Musashi can be modeled in her as completed version. You won't have the instructions for that but it appears it can be done. It looks like any questioning about whether I would buy the Yamato are now put to rest...gonna happen.
As for Yorktown I've seen the hull--although I haven't scoped it out yet--it looks correct to my eye. She needs a full deckload--which you don't get here--but that's easily remedied; I'd like to see my kit built up as Yorktown right before she launched the morning strike which laid waste to Soryu. Overall she looks real good and definitely larger than her Tamiya counterpart--Tamiya's kits in the stash are now so much offal for Ebay. It's gonna be difficult to find a better flattop for the money or the scale.
As for sourcing there be Doyle's fine volume and Wiper's monograph, not to mention the final word by Cressman although that would be more for the armchair historian, not the armchair naval constructor.
Once again, I'm not embarrassed by the riches we see these days; no one else should be either.
