There are a lot of Santa Maria different drawings. I have 13 or 14 of them, don't remember right. Most competetive work, despite "versions" of Santa Maria, at my opinion, is allready mentioned book by X. Pastor.
Revell's Santa Maria is based on reconstruction by Julio F. Guillen (1927, as caravel). Todays naval historians say, that can be, that replica on reconstruction by Jose Maria Martinez - Hidalgo y Teran (1964, as nao) should be most alike real Santa Maria.
