I am guessing the staggered spacing was to provide better coverage, basically fill in the diamond shape created by non-staggered spacing between 4 heads.

At that time you only had 1/2 (5.6K) and 3/4" (8.0K) sprinklers. You may also find some 3/4" pipe used on old pipe schedule systems.

What was the reasoning for this back then?
