One note of interest is that the glass factory roof accident occurred exactly 115 years ago today. November 29, 1900 ~ November 29, 2015 ( This photo was taken just minutes before the accident occurred ) [attachment=Pacific Coast Glas...ember 29, 1900.jpg]
John : Thanks for participating. When you take into account the findings of fairly reliable sources, such as ... 1. The PCGW (Pacific Coast Glass Works) mark was used between 1902 and 19202. Shoulder script Coca Cola bottles generally range between about 1910 and 1920 ... the best I can come up with to date my Coca Cola bottle is Circa 1915, which is right in the middle of 1910 and 1920. Although patented in 1915, the first Hobbleskirt bottles were not issued until 1917.
This revised timeline may not be 100% accurate, but based on currently available information it should be close. Notice I added and highlighted the 1900 date where the roof accident occurred. Also notice the Fifteenth & Folsom Street address does not appear prior to 1900. I'm thinking the new plant where the roof accident occurred was called the Pacific Glass Works, but I need to do some double-checking to be certain.

1925-1930 - Pacific Coast Glass Company, San Francisco, California. P/C in a square. This mark was used possibly as early as 1919, but was definitely in use by 1925.
The different addresses had me confused, but by studying various resources, including newspaper articles, Google Earth, etc; I was able to determine the 15th & Folsom location is about two miles southwest of the 7th & Townsend location and that the "new" factory at 15th & Folsom was almost ready to begin production when the roof accident occurred on November 29, 1900. As to the name of the company at the time, it was called ... The San Francisco & Pacific Glass Works I do not know what became of the old factory at 7th & Townsend, but it appears they abandoned it and relocated everything to the new factory at 15th & Folsom. Hence, this revised timeline ... ~ * ~

However ... This doesn't explain the Illinois-Pacific Glass Company being located at 15th & Folsom as shown in this San Francisco directory from 1910 ... (There is at least one piece missing from the timeline puzzle but I'm not sure what it is) [attachment=Pacific Coast Glas... 7th and Irwin.jpg]
Perhaps Illinois Glass bought out the S.F. P. Glassworks between the years 1900 and 1910, that would explain it pretty accurately maybe?? And of course combined the two names of both companies........
Andy I thought about that, too. But if that was the case, then why don't the various 1902 through 1930 listings have the word "Illinois" in front of them? As far as I know, the Illinois Glass Company didn't enter the picture until 1930. But the most confusing part is the address for the Illinois-Pacific Glass Company being at 15th & Folsom, which we know was originally the San Francisco & Pacific Glass Works address. I double checked the 1910 San Francisco directory and confirmed that the Illinois-Pacific Glass Co. was located at 15th & Folsom at the time. Here's another listing I found in the 1910 directory ...

If you look closely at your last ad you will see that the president is Abramson, of Abramson & Heunisch who took over the S.F.P.Glass works in 1898-99. So I guess that Abramson & Heunisch were affiliated with Illinois Glass co. They combined the names Illinois and Pacific to form the Illinois Pacific Glass co, ( my Guess only) .......Andy
