Hi Kevin,
Karl-Heinz "Heino" Cordes served with 1./JG 54 during 1943 before doing a stint as an instructor with 1./JGr. Ost in 1944. He then returned to JG 54. I have a note that he received the DKiG but he isn't listed in the usual sources, though it is probable a pilot with 50+ kills would have received it.
crashlanded 05Jul43, FW 190A-4 (147132)
crashlanded 04Nov43 (combat), FW 190A-4 (142491)
No idea whether he is related to "Lok-Töter"
