Hate to say this Darren, but this isn't a Bloodhound Missile.
It's a British Army BAC (English Electric) Thunderbird Mk 2 SAM. The Thunderbird Mk 1 was developed to the same Operational Requirement as the Bloodhound, but was a pure rocket powered weapon using cruxiform fixed wings and moving tail fins which steered the missile in pitch and yaw. (Bloodhound had top and bottom Ramjet engines, fixed tailplanes and moving wings which steered the missile by rolling the missile then pitching it (known as Twist and Steer). It was a lot smaller than Bloodhound (the boost motors fitted to the Thunderbird were the Gosling 4, which were the same basic boost motors as fitted to the Bloodhound, to give a sense of scale), had a much shorter range and a smaller warhead. It was however easier to move about than the Mk 2 Bloodhound was. It was operated by the British Army from between 1965 and the late 1970s.
