The Trumpeter 1/350th kit was the same. Mine was an older (BB-35) but I think they do that as a regular practice.

The argument in favor is it makes the canopies look better. But there are many arguments against. Mine fit VERY poorly. Clear plastic is hard to cut/cast/glue/manage in general, at least IMO. The clear part ended up fogged anyway, gray or silver paint would look better.

I thought I'd do well making them, aircraft are my main subject of modeling. But they came out REALLY bad.

I could claim they did not fit right, I could claim the casting was jacked up, I could claim there were not enough stickers. All of those claims would be right. But in the end I am the one who painted 1943 fighter (3-color) paint on them, which is wrong.

I'll show the old ones I ruined next to one of the new ones when I finish one.
