Vintage Wedgewood gas camp stove or cooktop burner. Mostly cast iron construction with welded steel perimeter frame. Appears all original and complete. Likely pre-WWII, since the gas valves were sourced from Germany, per the markings. Has common pipe thread gas connection. I believe it’s 1/2″ male pipe on the end of the chrome tube, reduced to 3/8″ female pipe with bell reducer. Cast iron burners and grill components install and break down without tools. Built in San Francisco, CA.
