Thanks jchinuk for the picture and info, I sent a few e-mails to the museum but never recieved any replies.
So this was developed by Shorts Missile sytems (Thales) for possibly the Javelin or Blowpipe?
Its sat amongst a couple of 'enemy' A/A pieces (Argy Hispano and Iraqi ZPU-4)
The kit next to it with the stabilisers looks like some sort of Radar fire-control system for this thingy?
