The names 'filter capacitor condenser noise suppressor' are all for the same thing.
The condenser that is fitted to the distributor does the same job as the 'added' noise suppressor on the coil.
Incidentally, there is usually a 'noise suppressor' on the alternator and often one on the electric fuel pump.
MB mentions all these in the BBB job 82-20, second series book 1968-1972
