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.
