Looking for a source of a gas burner.
When I was a kid we had a square cast iron gas burner (worked on NG & propane). orifices were ~ 1/2 in centers and the burner was ~ 9 X 18 to 20 inches.
I don't need a cast iron burner but do need something that has a somewat even flame over 9 X 18 /20 inches and works on NG (propane in addition would be nice)
TIA for all input
