Michel,
I only had the chance to do a brief check - and while the text doesn't have suitable drawings, there are some gorgeous fold-out plans at the back of the book of three early Dutch craft, Scylla among them. I'd guess they are about 1/150 to 1/100 (it would be tempting to actually make a 1/72 model out of that...).
I have checked with the KB, but they don't seem to have it. Do you happen to have access to any German library? If not, what I can do is simply copy them onto A3 sheets and send them to you via surface mail (as I unfortunately forgot to take the book with me

that might take two or three weeks

).
