In AH the majority of the airframes has the most pimped out versions, for example: 109k, 152, p47m, f4u4 and f4u1c, spit16, la7, brewster.
I can see NO point why not add the 20mm version of this lil ride, rising her up from the hangar queen role. More than 1000 was built, more than p47ms, f4u1cs, f4u4s and 152s together (!) so idk whats the point.
In the other hand, the 12mm version can be added too as an EW or a scenario ride. I bet those versions dont require much 3d modification.
BIG +1
