Beg to differ, Craig. The Cambrian was sold only in North America and for a brief time was sold alongside Cambridges. As noted above our family car from 1959 to 1964 purchased from Fred Deeley Limited in Vancouver and it was most definitely a Cambrian. (Name was on the trunk lid.) The differences between the two models were apparently very minor.
Those little locating "tits" or tabs on headlights or whatever anyone prefers to call them have a name. They were officially referred to as "gizmos" in the instruction manual for the aimers I used many years ago.
