Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Maybe you heard of this from Bob Linsenman's book "Michigan Trout Streams"? He actually has a photo there of Hugh Beaman and some discussion of his streamer. Bob owns the Au Sable Angler shop in Mio. He has a web site and maybe you can contact them there for more info.
He says in there that it's a variation of the Black Ghost tied 8-12. Body is black wool ribbed with gold tinsel. It has a white hackle wing with either a red or yellow throat (hackle fibers) tied sparse and lightly weighted.
Hope this helps!
