How cool is your model project, Onno! Ever since I first saw a picture of the Bel Geddes liner as a child I've been fascinated by it. Did you know you can download (for free!) a good quality scan of the whole of Bel Geddes' 1932 book
Horizons, in which the liner (and many other projects) appear?

Also, a narrow strip is missing from the middle, doubtless due to the fold in the book.
Note that in the text Bel Geddes refers to a length of 1,808 ft, a beam of 110 ft and a displacement of 70,000 tons. The length seems disproportionate to both the beam and displacement. Filling in the missing narrow portion alluded to above (by continuing the curve of the second funnel) indicates an overall length of around 1,100 ft. Allowing for a margin of error in measuring from a VDU screen, one wonders if the 1,808 ft quoted in the text should actually have been 1,088 ft, not far off 1,100 ft? Such a length certainly seems more commensurate with both the quoted beam and displacement.
Anyway, hope you've not abandoned your model, good luck!
Incidentally, trivia lovers, Norman Bel Geddes was the father of actress Barbara Bel Geddes, better known as Miss Ellie in
Dallas! Not a lot of people know that...* **
*Actually, they probably do.
**To be said in a Michael Caine stylee.
EDIT: Just noticed that in the Popular Science article from April 1934 Onno included in his first post, the length is quoted as 1,088 ft, thus reinforcing my theory (above) that the 1,808 ft figure is a typo.
