F779 Sprinkler wrench

No sizes given but there shouldn't be any confusion... A search for the G in a triangle logo led me onto a Freemason rabbithole.

  2. Thank you very much! I'd agree it's Grinnell, though the logo I found was G within a gear (or sprinkler head I guess.)

  3. Bit of a tangent here. I spent just shy of 20 years working at Riverside Brass in New Hamburg ON. Biggest volume of castings were and probably still are fire sprinkler heads. Chances are if you see a sprinkler head in North America it was cast in New Hamburg. Really enjoy the blog btw.
