The Graham Glass Company was in operation from circa 1905 to circa 1928. So I'd say its highly possible they produced some Hutchinson bottles. But if they did, I do not know if and/or how they were marked.
Clarification ... When Bill Porter said Graham Glass did not use a makers mark until 1920, he was referring to Coca Cola bottles made by Graham and not necessarily other types of bottles, which could very well have been marked prior to 1920. After 1920 Graham started marking their Coca Cola bottles with an 'EG', 'LSQ', 'OG', 'G', along with their code for Coca Cola bottles which was the number '576'
On this example notice the 1916 almost extends beyond the RED in REGISTERED. It was described as having a solo 4 on the base but no other marks. The 4 is definitely a common denominator - just wish I knew for sure what it stands for.
Something that might help determine the meaning of the number 4 is to narrow down the location where the 1916 bottles are turning up. The one I just posted was said to have been found tangled among the roots of a tree on a creek bank in southern Connecticut. Which should be a good clue because it no doubt had been laying there since it was tossed away and possibly originated in that part of the country. I should have thought of this earlier, and will go back and see if I can discover what part of the country some of the other bottles originated. Regarding dates, it was around 1919 when they started embossing the town/state on the base.
Dm Thanks for the info. The last bottle I posted was found in Connecticut. Are the locations you listed where the bottles were found or where they were bought and/or shipped from? If found, that gives us ... 1. Connecticut2. Maryland3. Virginia ... which is not conclusive but appears to narrow it down somewhat to the same general region.
This chart is from the Bill Lockhart/Bill Porter article and is a list of what they claim are the first glass companies to produce the patent 1915 bottles. I placed a red star on those I think are the best candidates who might have made the 1916 error bottles. At this juncture I am working on the assumption that the 1916 bottles probably originated in the northeastern part of the United States. Your guess is as good as mine as to which of these glass makers, if any of them, actually made the 1916 error bottles. ???
Possible Clue ... In Bill Porter's Checklist book, he says ... "One of my favorites was Reed Glass in Rochester, N.Y. They used an 'R' in a triangle for a mark, and had blue bottles." He even underlined the word blue.
