for Citroen ID/DS with DV engine
|the 123\DV-R is essentially the same unit as the 123\DS-A or the 123\DS-R : it contains the same set of 16 advance-curves. The difference is its shape to fit certain "DV" engines, as Citroen 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.
Might you require vacuum-advance : specify a '123\DV-R-V'.
