Hi! Angolia believes that the order for the buckle swastikas was first sunwheel, then horizontal and finally the rotated swastikas. The sunwheel swastika was first illustrated in RZM publications as late as June '34. That said - many of these buckles pre-date RZM so it's safe to say that these were around long before 1934. In the Nash book, he also has the sunwheel swastika as making the first SA buckle appearance. He dates the buckle from 1923 - quoting number 6267 from the Steinhauer and Luck catalogue. Hope that helps. Rob
