HOLY S*IT! That is a lot. I know the "T" modle was used for aircraft carrier. What is the story with the "H", "C", "B","D" modle? Will we evey see any of these on AH?
H was kind of like the Ta 152H-1 we have in game, meant for high altitude with and extended wingspan. I don't know if a prototype was ever built.
One missing from the list is the A-0, which served during the Spanish Civil War, and the B, C and D saw combat in the SCW as well. The C and D served on through the Blitz of Poland but I believe it was removed from front line service before the Battle of France or soon thereafter.
I doubt we'll see any of them in AH.
Some things to note;
The original powerplant of the 109 series was the Junkers Jumo 210. This was retained until it was replaced with the Daimler Benz DB601 in the E, and from then on all 109s would have Daimler Benz powerplants.
The original armament of the 109 was only the two MG17 7.92 machine guns in the engine cowling. This was doubled in the C with the addition of two more MG17's in the wing. The pair of MG/FF 20mm autocannons in the wings were not introduced until the E-3.

The original armament of the greatly improved Bf 109F series was two MG17s and one MG/FF autocannon. Since the MG/FF sucked it was replaced with the MG151/15 15mm autocannon in the F-2. This was extremely inadequate and even when the MG151/15 was upgraded to an MG151/20 in the F-4 many pilots still wished for a heavier armament. Adolf Galland was tasked with testing a Bf 109F-4 with MG131 machine guns replacing the MG17s, but the guns were badly synchronized and the muzzle flash too great so the idea was shelved.
The Bf 109G-1 introduced the DB 605A engine and a pressurized cockpit, along with a plethora of other changes. The G-2 was essentially the same, minus the systems for the pressurized cockpit. The G-3 and G-4 introduced larger landing gear and a few other minor changes, the G-3 again being pressurized and the G-4 not. This repeated with the G-5 and G-6, both of which were essentially identical to the G-3/4 beside the addition of the MG131 13mm machine gun, the G-5 being pressurized and the G-6 not.
The G-6 was by far the most produced variant of the 109 with over 12,000 being built.
