I read quite a few books on the 109k, and yes a handful were given a MG-151 in the nose
* R I ETC 501/IX b or Schloß 503belly bomb rack, fusing equipment for fitting a 250 or 500 kg bomb
* R III Schloß 503A-1 rack for one fuselage drop tank (300 l/79 US gallons).
* R IV two 2cm Mauser MG 151/20 underwing gunpods with 135 rpg.
* R VI BSK 16 gun-camera in the left wing between nose ribs 3 and 4.
Here are the kits for the 109k - The bomb belly rack which im suprised is not in game, only has a drop tank,
the rack was designed for both bomb and DT.
R IV Should be an option for the 109k4, any buff hunter would enjoy having the extra firepower going
against buffs.
I go back to my origional arguement, re-add the Me109 g-10, and problem is solved.
