I found this photo many years ago during an aviation fair. It shows a Halberstadt C.V (at least that is written on the reverse side!) with apparently the observer/board gunner in a big hole in the fuselage.
There must be an interesting story behind this shot, but I do not know this. I think it could be a result of a mid-air collision rather than battle damage!
Anyone out there who can give more information? The photo is from the late Peter Grosz collection and I have also scanned the reverse side. The pencil writing could read: 'Fldw. Rosengard, Abt. III' not sure!
