This is how the ballasts are mounted in these three matching fixtures. The 2-lamp fixture has two single GE chokes, made in November of 1962, mounted under one endcap, with the starters mounted under the opposite endcap. The 4-lamp fixtures each have one GE two-lamp ballast and two starters at each end. Unfortunately I can't find any date codes on them.
