Nope. The designs never got past the concept stage so what you see is all the sources show. I've got one in Harrier colours but it's nowhere near done.
You can't just make up panel lines or something? That seems to be the case with SABA as I'm assuming it was one of those generic, unmarked engineering three views. It would go a long way towards improving the aesthetic either way. Granted at the distance in the drawings you wouldn't see any panel lines, but it just looks strange being so clean.
Which Harrier colours? GR.1? That would look great.
