I don't have the Campbell plans in front of me, but I believe you'll find a note about the after deckhouse alongside the little "scrap view" that shows the layout of the bunks, etc. in the forecastle (meaning, in this context, the little triangular space in the bow - the one with the little portholes). Campbell and MacGregor, in other words, say the same thing. I suspect MacGregor based his statement on the Campbell plans.
Steves's comments on the big portholes in the Revell kit are most interesting. My memories of the Revell Cutty Sark and Thermopylae go back quite a few years - far enough that my memories are not exactly a hundred percent reliable, but I can flesh them out somewhat with reference to Dr. Graham's book. According to him, the Thermopylae first appeared in 1960. It must have been shortly thereafter - maybe 1962 - that a lady friend of my parents hired me to build one for her; she wanted to turn it into a lamp (ugh!), and offered me the staggering sum of $5.00. I'd already built the Alabama and Kearsarge, so I felt well up to the task. They both appeared, according to Dr. Graham, in 1961 - in conjunction with the Civil War Centennial. I'm pretty sure I got the Alabama for my birthday that year and the Kearsarge for Christmas. So I think my first encounter with the Thermopylae must have been in '62 - or maybe '63. At any rate, I rather suspect the quality of the result was such that the client got slightly ripped off, but I, at the age of twelve, was proud of it - and she liked it so much that she abandoned the lamp idea.
I think it was the following Christmas - either 1962 or 1963 - that my parents gave me the Cutty Sark kit. (I'd told them I wanted it instead of the Thermopylae because my father and I didn't like vac-formed "sails.") This obviously was a long time ago, but I'm fairly clear in my recollection of an interesting little note in the instruction booklet, which explained that, though the painting on the box showed the row of portholes, the model didn't have them because they'd been cut after the ship's cargo-carrying years. (The kit also included a copy of a photo-illustrated brochure about the ship - one of the brochures that I saw for sale in the ship's gift shop when I finally got to see her for the first time, in 1978.) All this is consistent with Steves's assertion that the portholes got removed from the molds when they were modified into the Thermopylae. (I believe the little bumps on top of the rails, to indicate where the deadeye assemblies were to be glued, were added at the same time.)
The result of the changes, of course, was most emphatically not a scale model of the Thermopylae. She and the Cutty Sark looked about like each other from a distance; that's the extent of the similarity. This was, in fact, the first of several marketing stunts that Revell used to get additional mileage out of sailing ship kit molds.
Those original Cutty Sark instructions assumed quite a bit of interest - and financial resouces -on the part of the purchaser. The rigging diagrams were more sophisticated than the ones Revell put in later issues of the kit; they advised the builder to make jackstays for the yards out of piano wire, and to buy twelve feet of 36-link brass chain for the sheets and halyards. My father duly took me downtown to Hall's Hardware (a cultural landmark of Columbus, Ohio - with an excellent hobby shop in the basement) to buy the chain. It came in one-foot lengths, each in a little yellow envelope. When I asked for twelve of them, the clerk said "What are you building - a Cutty Sark?" That chain wasn't cheap; I think it was close to a dollar a foot. But my father calmly handed over the cash - and another buck or two for the piano wire. My jaw dropped; Dad wasn't the kind of man who spent money casually in amounts like that. I realize now what he was probably thinking: that building a model of the Cutty Sark was preferable to what lots of twelve-year-olds were doing with their time - even in those far-off, so much more innocent days.
Sorry for the stupid nostalgic ramble. As should be obvious by now, I do, despite the nasty remarks I've made about various sailing ship kits in this Forum, have some pleasant memories of them.
Steves - does your old kit have those rigging instructions, with the references to the chain and wire?
