Some nice work there.
I think I competed against it's previous owners, and not you.
I would think about fitting rear calipers with cables, a) to get a proper MOT and reduce hassle at scrutineering (they are a MOT and thus a BB requirement) and b) they are needed. As we found out at Abingdon when we lost brakes due to a burst hose, we lost all fluid and then all foot brake action. We only were able to slow the car down due to the cable hand brake. I hate to think what it would have been like without the cables...
