Let me know what logo is used if you still have original glasswhat year and model car you have Triple-M cars only pleaseand whether there are any date codes shown. How do you date a front wind screen for and are the side windows dated? Trade names: Now what does the dots above the XXX mean? Date marks.
I have been looking at TR6 windows lately and all I see are 3 XXX s in a straight line with triplex and toughened below it with a symbol and more letters below that.
Triplex Glass Manufacturing Date Codes
Glass Dating? Laminated and toughened safety glass, machinery glassware. Ah right, well that's fair enough, so to be accurate, you want one from a few Months to a year before the build date then. Pilkington gradually increased its shareholding in Triplex until by it became the majority shareholder. Does anyone know whether date codes were used on the "Triplex Toughened" logo etched into the glass of pre-war cars. Today they can still supply products with the original trademark. Of course, this method reveals the date of manufacture of the glass itself, not the car or hardtop it is fitted to, but the glass probably didn't sit around very long in the factory before being fitted.
