Thank you. Now that I have the machine's genus
and species, I have some information on it--a
modification of a civil aircraft, suited for take-offs
and landings at short strips. The type served
just about everywhere in the war; some were even
armed, and flew cloak-and-dagger missions
behind Japanese lines.
