Rat Faced McDougall

Originally starting as a fly named the Beaverkill Bastard, this fly invented by Harry Darbee in the late 1930's somehow was renamed Rat Faced McDougall. The story about the name change can be read in Harry's book 'Catskill Fly Tier'. 

A very similar fly called the Irresistible by Joe Messinger sr. looks almost identical. The Rat Faced McDougall having a hackle fiber tail rather than the more durable moose body hair.
