Logo glass

#1 Post by Brad Ripley » Fri Mar 15, 2019 12:51 am

Today's Question for the Pre-A Corner: What logos do you find
(1) door window SEKURIT or SIGLA ?
(2) rear quarter window? SEKURIT or SIGLA ?

Some guys say they should be the same manufacturer on both.
Some say the door is Sekurit and the qtr window is Sigla. What's the Truth?

From what I've seen:

1) Door glass was always SEKURIT tempered glass on all models.

2) Quarter windows early on at least through early 1951 were SEKURIT tempered glass, but eventually by 1952/53 it was SIGLA laminated. Perhaps they were tired of breaking the tempered glass trying to get it to fit inside the window frames, so they just went with the laminated glass and could grind it as needed to make it fit.

bonus) Rear window was SIGLA laminated glass.

James and Jesse,
Thanks for the info. From another source I have also learned the same: Door glass = SEKURIT ; Rear Qtr = SIGLA . Fortunately, the glasses we had made are correct with differing logos after all.

On our '55, born Sept, Sigla on the Qrtr Lights and front windscreen, and Securit on the door glass.

Can't say about the rear as the original was cracked and we've replaced it with the old stock Securit screen one of the previous owners had bought and never fitted & unfortunately, for this question, we binned the original.

Also when I was cleaning the quarter light glass, I found 55 was etched right on the edge glass which is covered up by the frame and seals. It came as a bit of a surprise and I haven't seen a date on any of the other pieces of glass.

If you want to get really complicated, dig into the "DOT" coding on the Securit logo. There are several threads on the Samba site that discuss the coding, but this table summarizes their existence on various models. (Click on the thumbnails for expanded pictures.) One thread suggests the manufacturing date is indicated by dots above and below the letters of the logo. Obviously this deals with VW glass, but at least some Porsche glass was similarly coded. (Brad is likely aware of the dots and may be able to define the codes more thoroughly.)

My original '53 windows shown below: passenger side with dots and driver side without.

I had new glass cut for my '53 cab - tempered glass but without the tempered cert and SECURIT laser etched onto the new panes (without any dots).
