Not sure how the hell i missed this one. Your definatly right in that this kit is certainly not a D-3. But you have made good progress on it.
The only 72nd decals for a G-2 i know of where by Microscale and they were for Rudels bird from 44/45. But i think they are long OOP.
If you ever want a really nice 72nd G, i would really recommend the Academy kits.
I am a Norfolk man and i glory in being so
