Hello Ginger
The only information that I can find on this fellow is the following loss list entry in the QM 6:
5 October 1943: Leutnant Hans Gest, Staffelführer of 2./Schl.G 1, killed in Fw 190 F-3 (W.Nr. 670 396) by return fire at Pl.Qu. 0278, 100%
From this it would appear that he was actually a Schlachtflieger or ground-attack pilot not a Jagdflieger or fighter pilot. When I entered these co-ordinates into the Luftwaffe Reporting Grid tool at
www.gyges.dk/LUMA.xls it resulted in the following map:
http://classic.mapquest.com/maps?l=51.041668&g=30.25 which would fit the area where I./Sch.G 1 was engaged in October 1943. I hope that this helps.
Horrido!
