My monitor isn’t big enough to let me study those plans in much detail, but they do seem to be identical to the Revell kit.
That does not, however, resolve the question of just how the ancestry of the kit - or the drawings - worked. Those drawings, from what I can tell, have a distinctively modern look to them - and the website doesn’t provide any information whatsoever about their origin. They certainly look like they might have been drawn after 1965 (the date when the Revell kit was released). I also don’t know when the Mamoli kit was originally released, but I think it’s post-1965. It certainly looks like the Revell version.
The Revell artisans obviously worked on the basis of a set of drawings from somewhere. What it was - and how old it was - I continue to wonder. Either the Revell kit was based on the plans that appear on the website, or vice versa - or both were based on some third, older source.
Papillon - do you know the date of publication of the German book you mentioned earlier? I haven’t been able to find a copy of it on any of the used book websites I normally check, and it doesn’t seem to appear in the bibliography of any of the books on the subject I have. A Google search on the name “Rolf Hoeckels” (and one on “Rolf Hockels”) came up empty. The title suggests that it’s a pretty important, and wide-ranging, book - and if Mr. Hoeckels did indeed draw the plans on which that kit was based he obviously knew what he was doing. If a copy of the book can be had for a reasonable price, I’d like to buy it. [See below.]
I really wish model companies would be straightforward about the sources on which they base their kits. Model Shipways, Bluejacket, and Calder usually do a pretty good job of citing sources; plastic kit companies apparently want their customers to accept everything on faith. And the HECEPOB companies would rather we just didn’t think about the question.
One way or another I’ll certainly close up any openings in that railing that actually would admit water under the poop. The stanchions inside the bulwarks alter the character of the inboard works of the ship quite a bit. (I’m also adding some hanging knees under the breaks of the quarterdeck and forecastle. One more detail that the kit doesn’t have - and the Revell Mayflower does.) They also suggest that whoever drew the plans didn’t pay quite enough attention to how such a ship would actually be constructed. As I was laying out the frame stations I quickly discovered that I had to choose between spacing them evenly or putting one frame on each side of each gunport. By the standards of later centuries it should, of course, be possible to do both. But we know so little about shipbuilding practices during the Tudor period that I wouldn’t want to pronounce the kit “wrong” in that respect - or any other.
Edit, fifteen minutes later - I figured out the problem with finding the German book: the author’s name is not Hoeckels but Hoeckel. (Papillon - your English is excellent; as usual, I’m embarrassed by my own ineptitude in foreign languages. But in English a possessive noun, with few exceptions, requires an apostrophe before the s.) A couple of searches for books by Rolf Hoeckel produced some interesting results. Apparently Mr. Hoeckel has published quite a number of books, including several on ship modeling. (As I’ve noted more than once in this Forum, the English-speaking ship modeling world would do well to pay more attention to what goes on in Germany and Holland - and, for that matter, Russia.) I ordered one from Barnes and Noble called Modellbau von Schiffen Des 16. Und 17 Jahrhunderts. The price was only $21.00; it should be here in a few days. I hope my primitive undergraduate German will be up to it.
At www.bookfinder.com I found several copies of Risse von Kriegschiffe des 17. Jahrhunderts. They had several different publication dates; apparently the book has been reprinted. The date of the earliest copy listed on that particular site is 1970. Perhaps there was an earlier edition. If not, though, it seems the Revell kit (which was originally issued in 1965) could not have been based on that source. (There is the fascinating possibility that Mr. Hoeckel based his drawings on the Revell kit - but I think it more likely that both he and Revell worked from some third source that we haven’t identified yet.)
Papillon - do you have a copy of that book with a publication date prior to 1965?
