Byron -

I have some of Jacklin's Green Drake flies that he calls Compara Drakes. They are similar to the fly you have shown, except that the tail is tied rather short with yellowish olive dyed deer hair, and the hackle is trimmed flat on the bottom. The wing appears to be deer hair dyed a dun grey color.

A friend had Jacklin tie a dozen of this pattern, plus some other flies, about 5-6 years ago, and gave me a half dozen of the Green Drake Compara Drake flies, all of which I still have, unused.
