Photo of 88mm Flak Battery or Cannon for upcoming book

[Bob Korkuc]

I am under contract with the University of Oklahoma Press to publish a non-fiction work on the loss of my uncle's B-17 on 25 Feb 1944.

On 25 Feb, "schwere Flakabeteilung 436", Heavy Flak battery 436, Units 1, 2, 4 and 6 scored hits on the B-17 at 1440.

I would like to include a photo of a typical Flak battery in my book.

I am seeking permission from Greenhill Books, to reuse a Flak Cannon from Dr. Alfred Price's "The Luftwaffe Data Book" but to date I have gotten no response. Attached is the image I am seeking permission to use.

Thus can anyone point me to another resource where I can obtain a suitable photo from?

Thanks in advance for your help!

Regards,
