Hello Martin
I checked the QM 6 documents and this is what is listed:
1 December 1943: Unteroffizier Helmut Johanning of III./JG 1 wounded in Bf 109 G-6 (W.Nr. 19 850) due to unknown causes at Pl.Qu. ML8/3, 75%
Note the different werknummer although I have noticed that occasionally the QM 6 has errors and so would I would rely more on the information that Prien provides. I entered the co-ordinates ML-8.3 of the Jägergradnetzkarte into the Luftwaffe Grid Map Converter at
www.gyges.dk/reporting_grids.htm and the result was
www.mapquest.com/maps?l=51.069444&g=5.305556 which indeed is nearer to Mol than to Nijmegen. I hope that I have done this correctly. Regarding Miksch, unfortunately the QM 6 lists both the cause and location of his loss as unknown. I hope this helps.
Horrido!
