A traditional wet fly for which more than one tying can be found in the fly fishing literature, though it is only mentioned in a few of the common 20th Century compendiums of trout flies. The oldest reference that I can find to the pattern is that given as a loch fly by Roger Woolley  in 1932. Roger Woolley’s book is a collection of articles first published in the Fishing Gazette in 1930 and 1931. The pattern simply says “Jay Wing”, not specifying whether it is the blue-barred feather or primary wing feather. The rest of the dressing matches that given in later dressings by John Veniard  in 1952, with a blue-barred jay wing (the version tied here), and in his later book Reservoir and Lake Flies . It is also the version beautifully tied by Ken Sawada  in his 1995 book “Wet Flies”.
Tom Stewart , writing first in 1964, suggests that the pattern has been subject to many variations over the years including the version with teal tail fibres and blue-barred jay wing given here. He then goes onto describe a “usual” tie as being red-dyed hackle fibres for the tail and a blue feather from the jay for the wing. Tom Stewart’s “usual tie” is the one given by Stan Headley  in 1997 using a pattern supplied by Davie McPhail.
As to Colonel Downman himself, there would appear to be little mention of him beyond a comment in the French magazine “Le Moucheur” by Maurice Lewkowicz who describes the pattern as having been created by a colonel of the Indian army retired in the 1930s though no citation is given as to the source of this information.
