Mini or Moke engine distributor water protector shield. 
This  large plastic distributor shield comes without any fittings or clips, to cover the engine electrics. The two upper brackets will fit on the rocker cover retaining nuts and the lower bracket fits on the gearbox with the square fastener hole towards the oil filter side.
You will have to remove the gearbox to engine bolts.
Start with the middle bolt first (there are total of 5 x bolts) so you can see where the bracket needs to be fitted and the bolt to the left, nearer to the starter is the other bolt needed to  be removed.
