Flamespreader for the 14''' Kosmos-Vulkan-Brenner

I just got a 14''' Kosmos-Vulkan-Brenner made by Hugo Schneider, but it has lost it's flamespreader.

Can someone here help me with the dimensions of the flamespreader?

According to Jacques Goldbergs "Die deutsche Lampe in Wort und Bild" the burner uses the normal Kosmos cylinder.

Never mind! I got an answer in another forum from a guy with the same type of burner. The device that looks like a holder for a flamespreader is most likely just there to control the airflow. His burner was marked "Kosmos-Brenner".
