A document named "obmed" (that I'm attaching for quick reference), circulating from years on the Internet, but whose source is unknown, states that the F-2 sub-variant of the Bf 109 virtually did not participated to African campaign (apart some F-2/B given to JG 3), and all "F" models were of the F-4 sub-type.
This looks to me in contradiction with photographical evidence, like in the following examples:
Moreover, a clear reference to the F-2/Trop sub-variant is made in history of the
JG 27 on Wiki:
"
In settembre [1941], il I./JG 27 fu raggiunto dal II./JG 27, al comando di Wolfgang Lippert, che sul fronte orientale aveva ottenuto 43 vittorie in tre settimane. L'arrivo del II./JG 27, equipaggiato coi nuovi Bf 109F-2/Trop, versione specializzata per le condizioni operative africane, consentì al I./JG 27 di tornare in Germania, uno Staffel (squadriglia) alla volta, per scambiare i vecchi Bf 109E Emils coi nuovi Bf 109 Friedrichs. L'intero processo richiese ben più di un mese. Con l'arrivo dalla Russia del III./JG 27, alla fine di ottobre, entro dicembre l'intero JG 27 fu nel Nord Africa."

Bf 109F-2 / Trop, a specialized version for African operating conditions, allowed I./JG 27 to return to Germany, one Staffel (squadron) at a time, to exchange the old Bf 109E Emils with the new Bf 109 Friedrichs. The whole process took well over a month. With the arrival from Russia of the III./JG 27, at the end of October, within December the entire JG 27 was in North Africa. "
I would like very much to be helped to understand how things went really, and especially what kind of machines operated with
JG 27 during first half of 1942.
