Seagoon,
your pics, probably taken from Robert Michulec Me109 part 2, shows 109F-4s "belonging to I/JG52, the first unit equipped with such F-4s and the only one which tested them under front line conditions". After extensive trials, with a lot of problems, the under wing armament was declared satisfactory (about mid 1942).
However, under wing cannons were not introduced in the 109F as its production ceased during late 1942. Actually, during late 1942 (the 20mm gun pods) became one of the most widespread mods in the 109G-2.
During 1943 this type of armament achieved its greatest popularity and was often installed in the 109G-6 (almost one third of the entire G-6 production).
Bruno knows very well how much I cried about the loss of the gun pods armed G-10. After a lot of digging and research I (like Michulec) couldnt find even a photo of a gun pods armed G-14 ... go figure. However late G-6 were (MW50 equipped) like the G-14s and probably still mounted gunpods, so our gunpods armed G-14 is probably ok.
Many authors state that gun pods have not been mounted on real G-14s, G-10s and K-4s, even if drawings and tech specifications about them exist.
