OK - Anyone got a spare power steering aluminium transfer pipe the passes in front of the radiator. 
Finally traced the last leak - appears to be weeping out of the joint just before the 90 degree bend to the reservoir - suppose there is little point in trying to repair this item.
Will also try local breakers this weekend but do not hold out much hope.
