Triplex - Sicursiv Climma Glass history

[Colin]

Hi Guys
I am looking for some information regarding glass in my S3 V12 2+2 1973
The car is about 250 from the end of the final production run and was built in June 1973 - last one built was about August 1973
I have owned the car since 1977 so in theory it would have been original.
I have an original Pilkington Triplex Sundym Heated Rear Window Glass - The windscreen is now a Pilkington Triplex Sundym which was installed recently
The puzzling bit is the rest of the glass (ie) 2 x Rear Quarters - 2 Door Windows are all SICURSIV ClimmaGlass -
I see that Sicursiv were also fitted to the MGBs and Minis after 1973 having previously used Triplex

This is more of a bit of history lesson for the forum rather than any issues with the glass as It maybe that all the 2+2 cars produced around June 1973 were fitted with the Sicursiv glass. To be honest I had never took much notice until my recent restoration where it was picked up.

So I wondered if anybody has information or indeed their car has the same Sicursiv glass

Thanks as always
