The image above depicts a JG 20 Emil on the airfield at St. Omer, a derelict Curtiss Hawk in the foreground. The same photo album (entitled 'JG20 in the French campaign' by the seller) contains a couple of references to Guenther Burgaller.. (see images below captioned 'meine Staffelkapitän' ) - this is presumably the same Burgaller who served with the 'Richthofen' in both WWI and WWII which must make him something of a rarity in Luftwaffe history circles. He served under Voss in WWI as part of the so-called 'Flying Circus' and was StaKa 1./JG2 on the outbreak of WWII. He was a well known racing car driver in the interwar period. He departed JG 2 in October 1939 for JG 51 but died in a crash in February 1940 as Gkr II./JG51 and must have been at least 44 yrs old at the time of his death. He certainly didn't get to the French campaign. He would almost certainly have been a contemporary of Walter Oesau's in Döberitz during 1939..
