That looks like the one to me (canti bridge could easily have been changed in design as it was handbuilt) and the electric blue colour is right as well (see pic 5 for one of several scapes revealing the original colour).
Was secrectly hoping for a Kili Flyer but wasn't counting any chickens. It looks like I have a project for this year then. Will need to get a paint job and some decals done a lot of cleans done and some replacement Deore MT-60 kit found.
Quite happy to have an 80's slack angled handbuilt 531 beast in the stable.
