They're British rigid airships, and my guess is that the photograph is at Howden. However, I'm prepared to concede that I might be wrong. Gareth
It reminds me of a picture in a book I have, but the book is upstairs where my wife is sleeping so I can't get it till tomorrow. If I'm right, it shows R27 and R29 and it may even be a painting rather than a photo. Adrian
Annie Yes, Howden was a major RNAS/RAF airship base for anti-submarine patrols over the North Sea. See Battlebags by Ces Mowthorpe, ISBN 0 7509 1518 8. Cheers Gareth
