Hello Timon,
That's an easy question. If you had looked at the Abschussliste of the III./NJG 1, the unit of August Geiger, you would have seen that he obtained this nocturnal victory with the assistance of Oblt. Drefkorn, Jägerleitoffizier of radarstation 4D (Toldijk)
Teerose was not involved...
Best regards, good weekend! Marcel
