If you want - I can provide you with the dispositions of the various JGs on both fronts, including the aircraft types on hand.
Hermann Graf's last mount was a K-4, Hartmann definitely flew a G-10 up to his 350th kill, although there's strong evidence he was flying a G-14/AM around October of '44 and a K-4 at the end of the war (by Hartmann's own account, so don't shoot the messenger). That being said, no photos of Hartmann's K-4 are known to exist. There's an interesting blog entry from a fellow Luftwaffe researcher that offers a viable explanation...
http://falkeeins.blogspot.com/2010/06/hartmanns-last-109s.htmlThe D-9s providing cover for the 262s of JG44 was actually a small group, the Sachsenberg-Schwarm or Papagei Staffel. These were the red-underbelly Doras we often see in the game.
As others have said, by the time Stab/JG301 received their Ta-152s, there really was no Eastern/Western front as far as air operations were concerned. Herr Reschke in a Ta-152 shot down a Tempest and 2 Yak-9s in the days of the war, so....
163s operated from Brandis...D-9s were active on both fronts, 262s were all over as well, and yes, they were used operationally with 234s on the bridge attacks at Remagen. 234s operated in Norway, with aircraft from Einskdo 1/(damn filter) F.A.Gr1 and KG 76 being stationed there....
Pretty amazing to think about it really - many of these aircraft arriving so late in the war and ending up where they did.
