I have Jan '60 Austin 850. Windows are exacly alike. no dots either triplex or toughened on RH rear quarter and a dot above the X on triplex but no dot on toughened on the LH side. So 1960 but a dot above the X on triplex indicates fourth QTR but thgis should be fourth QTR of 59 right? because fourth QTR of 60 would be too late right? 'Splain that.

Hehe ya what up? Thank you Roger.

I was aware of the missing dot for the year.
there is also no dot on TRIPLEX for the quarter/month.
can you explain that?

It is dated. The lack of any dot under the word TOUGHENED indicates a year ending in '0'. So 1960.

I have what I think is probably a 1960 first or second quarter, narrow latch right side quarter window. I cannot see any date dots on the Triplex Laminated etching. I only think it's 1960 based on my doors, and the glass in them which is dated, and the early latch type. The part is in really nice shape chrome wise with no pitting, just some light scratches in the chrome, even the seal is in great shape. Is it common to not be dated?
