One more example might prove interesting. When Corgi finally got around to making a 1:72nd scale BF-110, it decided to take short cuts so it might save a little money using the hybrid approach. As a result, when the early, C mark of the BF-110 appeared, people like myself were appalled to note that it had an E mark canopy along with a "bump" ( air intake ) on the plastic nose part that housed the forward armament. This, too, was a feature of the E, not the C mark. Worse, the nose gun array was uniform rather than staggered---an impossibility for any BF-110 mark. Also, there were small mounting notches under the chin of the BF-110C, which were obviously intended for the later mark's radar masts---which, of course, the C mark didn't have. Obviously Corgi intended to pass off the E mark features as valid for its C mark models in the hope that nobody would notice. But we did and, in response to the ensuing uproar, the new Corgi management manned up and decided to make important corrections in its upcoming BF-110 models.
Meanwhile, I and other collectors were stuck with the hybrid BF-110C. So I made some changes. I couldn't do much about the canopy, and the little notches under the chin didn't bother me. But the nose guns and that "bump" really bugged me. I sanded down the bump, drilled new holes for the guns and repositioned them in a staggered array. Then I redid the amateurish mottling on the fuselage sides and added some weathering and staining. The "before" and "after" pictures follow. Here's how the model looked as it came out of its box:
