Good point about the removal of decals I often forget that just because one person finds it easy not so for everyone My apologies but, I was just saying that sometimes things can be left on for example, some of the Kursk vehicles were still sporting their unique kursk markings well into the following year after that battle and, I have seen some SS tanks left for other SS divisions still sporting the original divisions markings even though that division was not even in theatre at that time.
I agree that manufacturers often get things wrong but, its confusing sometimes when even the history books also do this a lot of collectors often just do not care as long as the set in question looks great
