That’s a very interesting find my friend. There was a time when I would build a kit based solely on an artist interpretation. Then I started digging into the history of the planes I was building and found out that occasionally the artist got it wrong. I’m not saying that all of these beautiful drawings are incorrect but some of them are.
However Beauty is in the eye of the beholder. I personally have purchased numerous kits over the years based on the box top art work alone. So I can’t fault anyone for that when I’m guilty about it too.
I like the picture you posted but I don’t think it’s 100 percent correct.
But that’s the great thing about building models. A person has choices and can paint the wings purple if they so desire. It’s their kit so be it ! Having fun is what the hobby should be about.
Occasionally we all get into the typical rut of trying to make our builds 100 percent accurate. If that’s your thing then by all means go for it.
I do try to accomplish this when I build something new. But for me doing that research on a specific aircraft or tank is just as much fun as it is building up the actual kit.
Here’s a few pictures that I found on the internet that shows the leading edge of the wing behind the rubber boots in natural metal and not yellow.
Hope these help you on your quest.
This first picture also shows the chin turret is in natural metal as well.
Occasionally they were painted in Neutral Gray but they could also be found in a natural metal unpainted configuration.
This next picture shows the leading edge in natural metal.
Hopefully this will help you out along the way.
