Darn. I wouldn’t know a Piper airplane from a Boeing 747, but there was a prominent Scottish piper named William Laurie from about the era of your clue. So I assumed I was looking at a Piper.
William Joyce, aka Lord Haw Haw...hated (rightfully so) because he was a fascist Nazi sympathizer and convicted of high treason, executed January 3, 1946.
Good riddance.
Edit: why he was famous?..."Germany calling, Germany calling"...he was a broadcaster...And a prick, just sayin'.
(Pardon, nerves are a little raw considering what has happened today minutes down the road from my home...what a shit show!)
