A feather in the hat

[Ole R Nielsen]

A question which I have been unable to find answer to, is the symbolic
significance of a feather in the rimb of a hat, like Ludwig Von Drake has.
My searches keep ending up with unspecific references to mid-20th century
fashion and Native American traditions, suggesting that mr. Von Drake has
performed some untold heroic deed in his past. Both a general answer to the
meaning and possibly story references to this characteristic of his are
welcome.
