The 123CITROËN-DV-4-R (also known as 123DV-R) is essentially the same unit as the 123DS-A or the 123DS-R. The difference is its shape to fit certain “DV” engines, as Citroën produced in 1966 and 1967. This can easily be seen, by the two M7 – bolts sticking out of the engine, for mounting the distributor. This explains the different shape of this 123-ignition. This unit offers vacuum advance as well. it contains the same set of 16 advance-curves.
