Mr. Thomas, thanks for sharing those beautiful ancient pictures. The pictures are really very instructive. 
For me it is an unusual way of fuller introduction. The standard way in bladesmithing was usage of spring swage or swage blocks. The material from the fuller escaped sideways and formed a bulge. It is interesting that fullering did not weaken the blade.
