I have an old Esci F-5 something that came with a vacuformed base and support gear (like a tractor and ground crew). It came with Swiss decals (I believe), but Esci decals from back in the day were not the best.
Maybe I’m an oddity, but I’ve always had good luck with original ESCI decals. It’s when their kits have AMT/ERTL boxing’s that the decals tend to be of lower quality in my experience.
