S.E.T. aero planes

Hi
For some time I became interresting in the aeroplanes/projects of the former S.E.T. factory.
Now I could, until now, only find an old publication were I could find some information: Romanian Aeronautical Constructions 1905-1974.
Looking on the internet there is almost nothing new, most articels used the information of the above book.
Are there more publications were I can find more about the S.E.T. aeroplanes/projects?
My interrests are:
1. Construction/technical details (also drawings/pictures with these details);
2. All kind of dimensions (such as: Gap,Chord/Stagger/Track, etc.etc.);
3. How and in which colors were they painted;
4. History;
5. Pictures;
6. Others interresting details/materials.
Who can help me and/or were can I get it.
This all is pure for private use!!.
Thanks
Jan
