From what I've seen, it appears to be. I don't have the ESCI kit, but the photos of that release match exactly to the Italeri sprue setup, so the odds are pretty good. As for the model itself, Belcher Bits will be shortly producing the Canadair CF-5A/CF-5D decals, including the "Aggressor" Bort numbers, in 1/72nd scale. (He already has the 1/4th scale set out.) My dilemma: which of the five Aggressor schemes do I finish it in? (As one person PM'ed me to suggest, I can always buy the other nine F-5B kits and single F-5A kit and do them all!)
