I totally agree that if it happened, then it's fine in this context. As I said, thus far I was unable to find evidence of it, but I obviously wasn't looking in the right places! As someone said, there would have been plenty of them.
And, what's with the Lewis Gun on the top wing? I've looked everywhere, and cannot find a single piece of evidence that the Germans ever fitted one, even as an individual field mod. Lessens the historical accuracy of the whole project in my opinion.
