Mr Bond
What a fascinating photo. Judging by the gents standing around it is taken in the 1950s,
possibly in one of the halls at Farnborough.
The photo enlarges very nicely and the rocket looks like a test item for various wings and boosters
and probes. Could it have been something to do with weather or atmospheric testing? It is certainly heavily engineered, which suggests it is British. I cannot identify the aircraft fuselage in the background.
Sorry not to be of more help.
The gent with the cap might be a pigeon fancier, so could it be...
