Looking for an aircraft...
1) Single engine
2) Fixed wing (s)
3) 2 seats
4) "Between the wars" design
5) French engine but not a French airplane
6) Biplane
7) Has flaps on both wings
8) considerably smaller than the An-2
9) The country of origin of this aircraft is West of the An-2's Country of origin...
but could have been considered an Eastern Bloc country, at one time.
10) I figure I might need to clarify "Between the Wars" as listed in clue #4 as in between WW1 and WW2
