Some time ago I downloaded a couple of photos of the III./JG 4's Bf 109 G* engine cowling from the website here
http://www.museum119.cz/menu_an.htm dedicated to the AIR BATTLE OVER THE ORE MOUNTAINS on 11th September 1944 in Kovarska, Czech Republic. The photos show an apparently streamlined (i.e., without the bulge) engine cowling that might have belonged to either Bf 109 G-6/AS, Bf 109 G-14/AS or Bf 109 G-10.
This is all fine except that according to the available literature on 11 September 1944, then still recently formed III./JG 4 was predominantly equipped with the Bf 109 G-6 and also some Bf 109 G-14 aircraft.
Therefore, although the engine cowling was recovered in the Czech Republic, in my opinion it might not have been related to the aforementioned battle. This issue is important for me to try and establish whether III./JG 4 sported the Knight's helmet emblem as early as of 11 September 1944, or perhaps not after all.
Any comments/remarks will be much appreciated.
