The 1942 Yorktown (CV-5) and the one represented by the Trumpeter kit (CV-10) were different ships. The former was the lead ship of the Yorktown class, which also included the Enterprise (CV-6) and Hornet (CV-8). The later Yorktown - the one represented by the Trumpeter kit - was a member of the larger, and quite different-looking, Essex class.
The place to start on a 1/350 model of the first Yorktown, therefore, would be the Trumpeter Hornet. I don’t have the kit, but on the basis of the pictures of it that I’ve seen the conversion would be significant but not overwhelming. The big differences, so far as I can tell, were in the bridge structure, the tripod mast, and the radar. I’m sure there also were some differences in the two ships’ anti-aircraft armament.
Quite a few years ago I started a project to build a Yorktown on 1/700 scale, combining parts from the Tamiya Hornet and Enterprise kits. I got bogged down when I became aware of a major problem from which both of those kits suffer: their islands are ridiculously skinny. I got as far as fattening up my *Yorktown’*s island, and was confronting the changes that would have to be made to the flight deck in order to accommodate it when I got diverted by some other project.
I also bought a set of plans for the Yorktown from The Floating Drydock. Those drawings, which are reproduced from the Navy’s “Booklet of General Plans,” are fascinating. They illustrate a conspicuous mistake in the Tamiya kits - a mistake that’s been repeated by Trumpeter, and on every other Yorktown-class kit I’ve seen.
There’s supposed to be a huge opening (marked “Void” on the plans) at the front of the funnel structure. Why this gap was there I have no idea; it looks as though the funnel was made in two halves that didn’t reach each other. The gap is at least six feet wide (I don’t have the plans in front of me), and stretches from the base of the funnel to the cap. Its location makes it hard to see in most photos; that’s probably why all the manufacturers missed it. But if you look for it in the right photos you can find it - on all three ships.
I mention this mistake mainly because it would be easy to fix - on the Trumpeter kit or any other. Just trim back the front end of each funnel half, and built a shallow styrene box inside (the back of the box being the front of the funnel trunking proper). Easy to fix while the model’s under construction, but next to impossible once it’s finished.
Back to CV-5 - two excellent sources, with lots of pictures, are That Gallant Ship, by Robert Creswell, and Return to Midway, by Robert Ballard. The latter book, a National Geographic publication, contains some fascinating photos of the wreck on the bottom of the Pacific.
Hope this helps.
