Colors roumanian military aviation

Hai
For some time I am inquiring etc. everything concerning the former Roumanian aviation factory SET.
They build before the war for the Air Force some types biplanes which could be used for several purposes. Most types were two-seaters and they mostly looks the same, most diverences where the engines (power). One, civil, single seater was used for the flight Boekarest – Hanoi. Who can help me with information how and in which colors the several military types were painted? I am also interrested in a drawing with dimensions of the national simbol which was used on the planes?
Thanks Jan
