Originally as in, used from 1969-1985 for Continental. I am not making any statements about the 56-60 Mark II-Mark V.
And I wasn't testy really. Just wondering, how that I was saying was being percieved. I am very well aware that Continental owners of the 56-57 model will become infuriated to hear anybody claim the Continental name as marque to anything else than to their blessed 56-57 Continental.
