II./JG1 was not formed until after the Battle of Britain. It was formed from I./JG3, which did fly
in BoB and then later in the Eastern Front. When I./JG3 was refit with 109F-4's they remained in Germany and were assigned to JG1 (circa November 1941). The Tatzelwurm on all II./JG1 aircraft is directly from I./JG3, so you could model a I./JG3 diorama, it would be the heritage of our Gruppe.
