I wonder if anyone has attempted to backdate the Roden kit to a C-141A? The Caracal decals have markings for a couple, as well as for a NASA bird.
I looked into doing the conversion, but it would require a “Z” shaped cut on the aft fuselage, not a straight chop. I think the fairing on the spine needs to be removed as well.
There were a bunch of C-141Bs operating out of Hickam AFB back in the 1980s; I sure miss them. The MAC grey/white scheme was sharp! I liked it better than the Euro-1 “lizard” camo that followed.
