Hello Rick,
Doug Stankey and Larry de Zeng's "Luftwaffe officer career summaries" gives the following details, this could be the same man:
OERTEL, Ernst. (DOB: 1923). (n.d.) Lt. IV./JG 3.
See
link.
If he was a IV./JG 3 pilot, Dr. Jochen Prien's relevant Jagdwaffe volume will have further details.
Regards,
Paul
