Petro

And Garwood, yes, I have seen a ancient Petro oil burner.

Most of them must have been regional companies.

The only one I'd heard of is Grinnell Thermolier. Grinnell is most well known for automatic fire sprinklers.

ADude, Thanks for the post! I've always been nuts over early HVAC stuff. That was really interesting.
