The correct wick for the Superspeed NCD and Wonderlite burners is the 9207. This wick will fit any of the burners mentioned. Why Falks had all these different wicks when one would have done is not known. Presumably the fringed wick for the Superspeed NCD was a hangover from the Famos 120, and the side draught burners had to have a split-tailed wick. They were probably consolidated into a generic “Superspeed” wick later. --Guy Richards
