That's like one of the (if not THE) original sprinkler head designs from grinnell, I'm guessing 1880's or 90s? Shortly after Grinnell started?

It's a sprinkler head. The blue liquid indicates it will activate at 225*F.

Firefly wrote:That's right, the blue bulb is for a higher temp, only it is 286'F which is what blue normally signifies. 225 isn't a standard temp I've seen, however, 325 is seen sometimes.

There is something more special going on with this head though and it isn't related to the glass bulb.
Is it a upsidedown mount?

Is it made of Steel? Is it for a cold environment?
