Dan,
On refering to the entry on
Holm he indicates that 7(F).LG 2 disbanded in Jan 1943 although he then shows this unit being at Mariupol until June 1943. Rosch agrees with the disbandment date.
Unfortunately, I don't know what Barry Rosch used to build his list of codes - entries in the loss tables, Flugbuchs etc so cannot be sure of the source for his entry.
