factory windows

[Innuendo]

That glass is marked 1973, denoted by the DOT above the letter M.
As for it being factory fitted. I'd like to see the Production Broadcast Sheet.

Never would a '74 built car get '73 dated windscreen or any other glass.

It is still a very grey science.

I have the broadcast sheet for this car, has A09 on it. Obviously Acacia Ridge didn't fit them at that time and relied upon the dealer to fit like the stripes.

The dating on glass goes by quarters. I think this one is 4th quarter 1973 which is OK for an earlier 1974 HQ especially low volume glass like side glass.

The dating dot is done by year and by quarters. The dot above the M is the year. The dot under the (is it a 1 or a I) on the ASRI is the quarter. So it is final quarter of 1973.
This would date it OK if the Sandman is a first quarter build of 1974 if not the glass is wrong.

Pilkington Glass is a mid 1970's supplier to Holden. Previous to that all Holden glass was marked Armourplate and later Armourglas.
