xerj,

Good question.

Hmm, Biplane: Beech 17 Staggerwing series. Monoplane: Cessna AW
(Cessnas never had wing struts until 1945) or Cardinal, military, the
Mk. IX Spitfire. Twin biplane: DeHavilland Dragon Rapide. Twin
monoplane: DeHaviland Mosquito or early Cessna 310. Three engine:
Stinson trimotor (high wing version, the low wing was hideous) or
Boeing 727. Four engine: DeHaviland Heron.

Cheers,
Rick
