Worked on first gridded system in 1973. I remember a guy in our office doing calc's on a rolled paper storage job in 1971. If your project was calc'd it probably wasn't per 13 but more than likely one of the storage pamphlets like 231C or whatever is was called back then. Existing 0.5 denisty with LH pipe scheduled mains and 80-90 sqft. spacing is curious.
