What Ulfbert said. These helmets were made in large quantities and in order to keep the plates for each one of a set together this sort of matched punching was sometimes used. There was a second punch method used where it was sequential used to keep plates of an assembly ( usually arms or legs ) in their proper order where some of the plates look similar in sequence. I've owned examples of both over the years and used both punch methods when I used to make armour for a living.
