Pattern Bill Chinn Nicholson

I saw a Bill Chinn fly which shows another version of the Nicholson When I first saw this fly I couldnt resolve its contents against any known version of the pattern. Then I saw a picture that was similar in Earl Hodgsons "salmon fishing" ca. 1907. Anyone elso have a source for this version, or one similar? I've also attached a version that I tied some time ago I call "Nicholsonia" It aint no Bill Chinn fly! :eek:
PS: as soon as I resolve the "file type" problem, I will post the Chinn fly1
:thumb: Thanks again Jerry for posting this fly by Bill Chinn. It speaks for itself: simply in a class by itself: perhaps something to shoot for.... :beer2:
