It lies somewhere between a Nord 3201 (not the Nord 3202), and the Fokker S-11. (Yes, I know the Brazilians built a S-11 knock-off, plus a tri-cycle gear version as well). Perhaps a license-built version combining the best from DeHavilland's DHC-1 Chipmunk, and the worst from the Hindustan HT-2. Is it from the far-off Islet's of Langerhan..?
