For those of you with a nostalgic streak (and years of experience as ancients wargamers), Sue Laflin Barker has put up a webpage with the scanned in early versions of WRG rules.
For someone like me, who has come into wargaming in its golden years, the fact that the staple figures seemed to be the various Airfix plastic sets, is quite refreshing :). In true Ourobouros fashion, it seems that in these days of figure cornucopia, history has turned around on itself and recreated gaming with soft plastic 1:72nd scale figures as a sub hobby on itself.
