Sorry Ard. I've still to get round to tying a Silver WilkinsonDo you happen to have a Silver Wilkinson you could post or if it's already here just say so? We are about to do a forum tie along exercise on the American forum and that is the starter pattern. I tied the classics back in the late 70's and early 80's and have now (along with my material collections) been broken out of mothball storage to participate on the thread.
If you had an image to post of one you tied I would offer it to the other tiers as an example of the perfect tie with credits to you of course.
