Thank you very much for your answer and your interest.
If someone is interested in Ictineo-II, I'm building a RC scratchbuilt 1:10 Scale. I show you sometimes ago a draw of the plans, made with Microstation (Autocad).
The main source of information of this incredible and marvel invention in the submarine history, es the book that Monturiol wrote, describing their invention. Moreless 50 years after, when Peral, another submarine inventor from Spain, built the "Peral", the book was published.
There is a facsimile of original book, with a complete description of their machinery and the "underwater steam engine" which he used as propulsion and too, as source of oxygen. Also the book has a facsimil of the original drawings. The book is named "Ensayo sobre el arte de navegar por debajo del agua, escrito por el inventor del Ictíneo o Barco-pez Narciso Monturiol"
For me, is the main source of information. Also, some biography of Monturiol, and pictures taken in "Museo Maritimo de Barcelona". In this museum, there a static model 1:10 scale exactly the original one.
The book is in Internet http://www.lluisvives.com/servlet/Sirve ... /index.htm
