Hallo kapudan,
Yes, Lusci's plans are available, for several ships including the "Spanish Galleon of 1607" as his "Revenge." You can get them from a firm in Italy. I'm away from my desk, but try a internet search using the terms Lusci, galleon and Revenge.
Lusci's "Revenge"appears to be the exact same design as the Science Museum model, so much so that I think he either copied their reconstruction completely, or modified it only slightly. Its a very good reconstruction, with finer lines than the Hoeckel reconstruction. Both are based on the famous Matthew Baker drawing of a large, four masted galleon, but with a stern gallery added.
The Baker drawing represents a ship of 546 tons burden or slightly larger, with a half deck, quarter deck and poop deck. Its larger than the actual Revenge by about 100 tons burden, and probably one or maybe two of the aftercastle decks. This is why the science Museum suggested that the drawing represented a larger ship, the Elizabeth Jonas, as she was rebuilt later in her career. However the decoration in Baker's drawing is too old fashioned for the rebuilt Jonas - in fact the drawing represents a ship much closer in size to the Victory and Ark Royal, although the Ark Royal, I think, had a two deck forecastle.
For some reason, the Science Museum omitted the quarter deck on their reconstruction, which is clearly evident in the Baker drawing. Daeffler's new work on the forms and design of Elizabethan and Jacobean warships correctly reconstructs this drawing with the quarter deck. Airfix, to its credit, also added the quarterdeck, although the resulting ship (and Baker's drawing) is too large for the actual Revenge. This is why its a great large ship, perhaps Victory is something like that, if not Revenge.
But back to Spanish galleons.
The Konstam book is a handy reference for Atlantic operations (curiously, no Pacific) but nearly all of the reconstructions are useless, and at least one of the images - an English galleon, with the coat of arms of Englad clearly evident on its stern - is labeled a Spanish warship. Of the reconstructions, only the first and the last are reliable. This is because the first is based on data from a shipwreck excavated by professional scholars, and the last is from a later era too well known to make serious mistakes, although it looks suspiciously Dutch. I didnt see any images of Spanish ships with the gun deck arrangement used in Lusci's plans, either in the book or elsewhere, however.
I think the main point is one mentioned elsewhere in this thread, that there are a lot of suspect older reconstructions which can look good but contain serious flaws. We can respect what they did, and also look for better information.
