In https://math.stackexchange.com/q/2602271/682690this MathSE question, Classificationclassification of Simple Groupsfinite simple groups with Abelian Sylow 2 Subgroups-subgroups, credit is rightly given to John Walter. But in the introduction to his paper, Walter explicitly states that "It seems to be a very difficult problem to show that these are the only examples." Is there a later reference, perhaps earlier than the complete classification theorem, that states that Walter, et. al. found them all? Thanks for your help.
