I was after the 22 litre top box.
That's it. It looks like it has its locking pin. Do you have the mounting plate that fits on the rack? That is a necessary part.
This.
How does it mount onto the rack then?

Indeed. If that can't be reproduced at a fraction of its cost by one of Her Magesty's loyal subjects using tin snips, a biscuit tin and a teacup full of spliffs, the world is indeed off its axis.
As per requested, the first one I bought has a manufacture date August 1985. I replaced four of the original rivets with bolts due to the plastic tab inside the box that holds the lid restraint system being broken off. I also added a bit off para cord as a precaution. The hinge looks to be original it has a metal reinforcing strip on the inside of the box to stop the rivets pulling through, this strip is not on the later box. The second top box with the metal hinge was manufactured in May 1986. A mate has a couple of 22Lt boxes but I believe they are a lot later in manufacture, I'll check when I can.Regards Martin. 22Lt Top box hinge..jpg (41.19 kB . 768x576 - viewed 387 times) 22Lt Top box Lid Restraint.jpg (49.91 kB . 768x576 - viewed 381 times)
