Kinda new regarding glass bugs which is why I started a new discussion. I've found 2 different bugs on my glasses. The driver wing glass has AS-2 above a rectangle that has Hi-Test within it and the letters SLG-M1 below the rectangle. The other bug is on the passenger roll up window and has the word Laminated above what looks like a 3-leaf clover with the word Safe at the left and Lite at the right of the "leaves". The letters M19-Dot65AS2 are beneath the emblem. Are either of these period or later replacements? No other "bugs" are on any other windows. Thanks for your help.

They are replacements.

The rest of the windows have no bug. The car was built summer of 1945, at least that is what research shows so far. Would the new glass have been unmarked at that point? The reason I ask is that I read somewhere that parts supplies for the cars were sporadic at best during the early months of production and parts were put on cars just to keep the lines running. Example: some cars came off the line with fenders painted on the outside, but the inside was either just primed, painted black, or had the body color painted on them. Reading those accounts made me wonder about the glass. Thanks again for your help.

The trade mark on the glass was put there by the manufacturer to show that it was safety glass and not ordinary plate glass. Not sure if it was a government requirement but I would highly doubt that it was not put there because of the frantic pace of producing cars in late 45. But here's another thought for you. If there are no markings, how do you know that you really have safety glass in your windows and not just ordinary plate glass?

There is one that has no marks, but has delaminated around the edges of the glass. The rest I will have to check. Thanks for the input.

When I replaced the glass in my '47, the supplier asked me if I wanted the "bugs". I asked him to put them on. At the factory, glass was marked as it came down the line lying flat, so the bugs can be on either side of the glass, depending when it was installed. I doubt that much original glass has survived. From time to time I have seen kits to put the bugs on. The Club's excellent 41-48 book shows full information on page 1-19 regarding the "bugs". If are planning to replace old vehicle glass, carefully check the thickness with a good caliper. Many nonspecialist glass shops don't stock the proper glass, making installation difficult or impossible.

I am fortunate and count the blessings to still have the original glass and bugs on my '47. The bugs' orientations are: Outside - of the passenger side door windows Inside - of the passenger side rear vent window Inside - of the driver side door windows Outside - of the driver side rear vent window Inside - the driver side windshield Outside - of the passenger side windshield Outside - of the rear window glass When viewed from the outside all bugs printed on the inside of the glass read in reverse. The '41-'48 Ford book makes mention of the left side/right side inside/outside result that supereal mentions, also on page 1-19. I noted the same, identical orientation to the above on a few other '46-'48 Fords and Mercs I've looked at but have no idea if this was an 'always' or 'sometimes' result, or if this was the standard at all for other years. I've also viewed fully restored cars with all the bugs printed on the outside of the glass. If you do not have adequate original glass to determine which 'corner' of the window the bugs were originally printed on, talk with your glass supplier and also reach out here to determine the proper location if you are shooting for or planning down the road for an 'as original' car. Unless you are absolutely certain you are working with original glass do not trust what is on the car as it may have been changed previously and the then owner may have mis-advised the glass supplier on the location (they'll put it exactly where you tell them!).

Just had a chance to read all the responses. Got and read the 41-48 book again. Thanks for all the input. It's been a big help. I'll replace the glass sometime in the future and be sure to have the bugs put in the correct places.

You can get the kit from Michael Driskel and put them on yourself fairly easy and get the code you want. Shiny side up! Cecil/WV

I may be wrong but at least in the '40s it seems to me that Ford made and marked all their side glass and it typically sat in storage for 2 or 3 months before being shipped to various assembly plants. The windshield panels were usually additionally ground and polished and made/marked by PG (Pittsburg Glass) as "DuPlate" or LOF (Libby Owens Ford) as "Hi-Test Safety". The slightly curved rear glass was usually made and marked by Herculite because Ford did not have the facilities to make curved glass.
