Large (and high in the air) freezer warehouse having double interlocked pre-action system where the owner has observed the air compressor on one of the four systems has been running more often than the other three.
Finally found the problem.
There is nothing in the building that would go this high to hit the head and with no fresh marks we tend to feel this head was damaged during original installation in 2001.
Dark ceilings where the lights are below the sprinklers; you couldn't have found this with a set of binoculars.
Seat still intact and it still holds. This one sits in my trophy case alongside my 1912 head.
I've never seen a head this damaged that would still hold.
