Aldon Fast Road Distributor - 59D - Yellow
Uses the same advance characteristics as 100AY but has the later type drive dog to suit 'A' plus blocks in the metro.
Aldon have been successfully modifying distributors for many years. They are now probably the only people in the UK, if not the world who specialise in this type of work. Aldon have customers throughout Europe, Asia, Australia and America. The units that are supplied / modified are based on Lucas distributors.
