Hello, your construction looks good so far.. but Im not sure about the zimmerit..I may be mistaken, but I dont recall any Ds having zimmerit applied. Also, unless it was riddled by a P-47 from all sides, I think the zimmerit chipping is a little overdone. It did occur, but mainly from tank shells, or straffing aircraft. and one last thing, the seam around the cupola should be filled and sanded smooth, its suppose to be one solid cast ring. hope I dont sound harsh with these.
