Title: Glass Date Coding.
Reason: To advise Dealer personnel of method of checking the date coding on all glasses (windscreen, rear screen and door windows).
  1. The year of manufacture is indicated by a dot UNDER the letters of the words 'LAMINATED' or 'TOUGHENED', the last digit only being indicated (i.e. 2 = 1972, 3 = 1973).
