I did check some of my photographs:
the 1936 buckles I have on photo all have the sharper edge. Some I see do NOT have the year,
but only the manufacturers code (Gebr.Gloerfeld, Overhoff), but are according the 1936-standards
(even gold versions);
the 1937 versions do have the rounder edge.
I see this feature also in Angolia, where a 1938 version is shown with the rounder edge also!!

I guess that late versions then got the crimped backplate. But most often these are not marked
as were the standards from 1936!
