A P38... saw one at an airshow in Sonoma county, Ca recently, along with a couple P51's, some Yaks, an A26, a P40, and a Sea Fury, and the 38 dominated the tarmac. I don't think there was a better looking or more graceful plane (both on the ground and in the sky) north of Chino.
Everything about it is smooth and sleek. Looking at it head-on, though, it was menacing.
However, a very good case is being made for the PBY by a few of you.
