Hi,
Thanks for the kind words, Kirk. Actually, Kirschstein flew two (possibly more) superbly striped Fokker D.VIIs - presumably the second was a BMW-engined Fokker. There are more photos than I once thought, but I'm not really at liberty to say much more.
Besides the very poor photo printed in my JG I book, one other photo of a different D.VII of Kirschstein appears on page 237 of Lance Bronnenkant's superb and astonishing new book,
The Imperial German Eagles in World War I, their Postcards and Pictures, Volume 2 from Schiffer. This is a direct nose-on front view that is much sharper than the poor photo in my book. There are subtle differences that indicate that these were two separate (but very similarly-marked) aircraft. I cannot recommend Lance's book highly enough.
The amazing thing about both of K's D.VIIs is - there was hardly any component that wasn't striped! Struts, undercarriage, all surfaces of both wings - everything.
