Hello, the plans of the line ship La Santisima Trinidad, possibly lost in the Napoleonic occupation. It is said, I have never seen him, that they are in a Russian library, or in the Library of the Congress of the United States, they can be. The line ship La Santisima Trinida, was built in Havana, and the archives currently in Havana are not properly classified, or with the entry of the United States were taken to the congress library. In any case, there is an arsenal model in the Naval Museum of Madrid, which is attributed to La Santisima Trinidad. With respect to the line ship, San Juan Nepomuceno, there are models, and even a central section of the master frame, to observe the differences in the constructive system (the French style) Nepomuceno, and the San Genaro (to the English). On the color of the most holy trinity, look for the paintings of the Spanish painter Carlos Parrilla Penagos. He is a great scholar in his paintings. At the Battle of Trafalgar, an English survivor told the Holy Trinity, with red stripes on its batteries and a thin white line between it and the black belts.
