15EFTS Tigers photo query

Hi Dan. I hope this is no imposition, but I am a graphic designer working in Canada on a magazine which is featuring a story about the restoration and flight/s of a DH.82 Tiger Moth. A sidebar outlines the history of the Tiger Moth, including its role as a trainer. I came across your beautiful photo of the three in flight (15EFTS Tigers) and was wondering if we could use it to accompany the sidebar. The magazine in question is In The Hills (http://www.inthehills.ca/), a small local publication (42,000) for which I am extremely proud to work – but please do review the link and judge for yourself. If you are amenable, the file I can access here is large enough for print (6″ x 4.5″) but if possible I would like to credit the photographer and include some details (if you have any) including the year it was taken. Please let me know if you would like any more details. Thank you in advance! (ps: I hope you can reply sooner rather than later; our magazine goes to print on June 6, 2014.) Kim
