I may be off the mark but I believe a FLETCHER has to do with bows and arrows. The feathers on the arrows are fletches and I think that a fletcher is a person specializing in the fletch to make an arrow fly just the way an archer wants. It will be interesting to find out whether my understanding is a bullseye or totally off the mark!
wow
P. S. When he was a young man my Uncle Charles hunted birds with bow and arrow as he thought it more sporting than a gun. Also he killed only what he needed to eat. Now in his 90s he "hunts" only with a camera.
