Can we identify whose Stuka this is?

[Ian Jewison]

Gents,

I have three different photos of this Stuka, all the photos belonged to members of 7/Stuka 1. However I am unable to determine whose aircraft this was.
None of the photos show the aircraft Werk-Nr. or Kennzeichen....apart from J9. Also the date 1.10.1941 is the date I presume of his 300th Feindflüge and not the date of the award of his RK.

As far as I can tell there are only three possibilities:

Obstlt. Walter Hagen. III later Geschw.Kdr./St.G. 1. RK 21.7.1940. FF?
Oblt. Hartmut Schairer. 7/St.G. 1. RK 30.8.1941 over 150 FF. + 19.7.1942 562 FF.
Lt. Theo Nordman. 8/St.G. 1. RK 17.9.1941 over 190 FF. By May 1942 he had 500 FF!

Not possibilities.......

Hptm. Helmut Mahlke. III/St.G. 1. RK 16.7.1941. 159 FF.
Hptm. Peter Gaßmann. III/St.G. 1. RK 25.5.1942 after 300 FF.
Oblt. Karl-Hermann Lion. 9/St.G. 1. RK 4.6.1942 after 368 FF.

It can't be a Bordfunker as Obfw. Heinz Bevernis was the first Stukaflieger to be awarded a posthumous RK as Schairer's crewman.

Any ideas/help would greatly be appreciated.

Thanks,
Ian
