I know that at least during the 1960's and 1970's, there's also a dating code on the windows of the British Leyland built cars, although I've never looked up this code

Hi Jan,

I have also used this Lucas date code to check a vehicles age, but over a long life these parts could have been changed. Another point is that the parts could have been in stock for some time before the vehicle was built, unlike today with the "just in time" approach to stock delivery. The year is more important than the month or week, because of the above reasons.

The date code on glass was not just on BL cars, it was used by Triplex on all their glass at the time and was dated by the position of a dot above or below a letter of the word Triplex. I cannot remember the code now, but have seen it written somewhere.
