My thanks to you both, Christian and Andreas, for the information.
It fits exactly with what I have been told from a Ludwigshafen historian, who has been researching the event, as he witnessed the crashed aircraft a day after it was brought down. His precis of what happened is on my website under "Hunters" and confirms the pilot as Heinz-wolfgang Hoppner, and the crewman as Alphons Low. Tim Woods record of German claims gives the Staffel as II (not sure if it is Eleven or two) But my German contact has it down as 6. NJG1. The aircraft and Number are confirmed as Wn- 5356, Aircraft Me110, G-4 and Low's rank as Unteroffizier. The base was confirmed as Erbenheim, between the towns of Mainz and Weisbaden. The Americans use it today. My contact is publishing the info in the "Jagerblatt" magazine, to see if he can dig out more.
Thanx again... Keep Looking:-)
