scroll about 2/3 the way down to Part 211: 1899 (Sprinkler System Installation Rules) The earliest Systems were installed based on British Standard Rules and, even today, the British pipe schedules are more 'lenient' than American schedules. I know Roland told me next time I tried to figure out where the max 32 ft/sec came from to take a hammer and smash my thumb instead... I think the British increased pipe size when the velocity got to 32 ft/s, and the Americans increased pipe size when it got to 20 ft/s.

Staggered spacing was quite common before 1940. Newer heads installed? High pressure water supply connected? It likely will barely do .10 density or maybe .15 with moderate pressure. FM used to allow 3-5 psi at end head for pipe schedule.

On the top floor, the branch piping is 3/4 - 1 - 1. Was there an older version of pipe schedule that allowed smaller pipe or is this just undersized? Hopefully some of you history buffs (or at least those with a bunch of old stuff) would know.
