This picture is easily enough found on the Internet, usually being identified as the Vickers Vigilant. However I've been wondering if it is actually a further development of the Vigilant that was ultimately not proceeded with.

It does share a lot of the same features of the production Vigilant, such as it's transport box/launcher, and MCLOS guidance, so it's possible I might be going down the wrong track here. Opinions?

One-Man Antitank Missile (July 1962)

Compact enough for the ordinary infantryman to carry into battle on his back, an antitank-missile system is simple enough for a nonspecialist to operate and powerful enough to destroy any tank.

The 44-pound missile assembly (bottom) is easy to set up and ready to fire at all times. The operator (top), using a six-pound sight controller, can change the missile’s direction with a thumb-tip control.

By the way, here's a 1959 Flight article on the development of the original Vigilant:

Illustrations in John Forbat's 'The 'Secret' World of Vickers Guided Weapons show trial rounds and boxes etc. They seem to match what you've shown above. There seem to be launcher boxes with and without cut-outs and the missile looks identical.
What exactly in the pictures you've posted makes you think this isn't the bog standard Vigilant?

Thanks lads. Partly it was the markings on the launcher in the bottom picture, and partly because I thought there were subtle differences in the design of the in-flight missile compared to the regular Vigilant. Looks like I was on a wild goose chase though.
