It is always interesting to delve into the background on the 'eye sign experts' and to see how well they were able to capitalize on their skills. Growing up in the 50's we read and re-read Bishop's book a hundred times and studied the eyes and numbers until we knew them well. I started my library in the 60's and lo and behold I purchased a book written by a Belgian who ruthlessly attacked Bishop for being a liar and more. In this book were actually photocopies of letters by Bishop basically asking the Belgium to send over some birds and he would whip some eye sign on them and sell them. I have Flemming's book and the only mistake he made was trying to race in California. Like feather merchants they should leave the racing to people who know how to. Most recently I was visiting in the hot bed of racing in the States,Spring Hill and checked out Pete Pobor's results.(he also wrote a book on eye sign). In a word they were poor. If it works for you great..but I'm skeptical after 50 yrs.
