Original spares for Miller distributors are now almost impossible to find, but providing the body of the rotor arm is sound, a new contact and spring can be cut from sheet metal. Any condenser from a Lucas distributor can be utilised - they don't seem to be voltage critical ( I have used Vauxhall Viva condensers in the past). The points are more difficult to obtain - they were only used in the Dragonfly and one model of Scott and, I believe, the Trojan van. Similar points which can be modified were used in the Siba Dynastart that was fitted to Villiers engines for use in invalid carriages - in fact they used two sets, one for forward direction and one for reverse!
