I apologize, I did not mean to sound as though I was "talking down to you". I've been practicing being a curmudgeon and sometimes it bleeds over...
For documentation, your best bet may be the Cuban Aviation site: the red, white and blue Sirius of Menéndez Peláez is a striking plane. That seems to be an interesting site: a Cuban site hosted by a Russian ISP.
Good luck!
