They look like AGM., products to me as well, but several firms used that style of burner, some better photos would help, Jeff.
I don't think these are AGM. The AGM version of this burner has the control spindle passing through the side of the cowl. These have the control spindle above the cowl which means they are Brite-Lite or Albert Lea Gas types. However they are odd because I have never seen one of these with those quatrefoil vents. So it is a new one to me. I know who patented it which is George Washington but who made them is a mystery. ::Neil::
