I’ll gloss over all that and share what seems the most accurate. You can guess from the title of machine what it did.
The automatic bottle-making machine revolutionized the industry, and became the foundation of today’s glassmaking industry. forming the company it is now (with a few changes along the way).
The number on the right is our year code and what we are most interested in. In conjunction with the relative dates of the symbol, we know that the 9 could either stand for 1939 or 1949 (1959 is possible, but very unlikely).Our first example to the right (Exhibit D), fortunately for me, is extremely easy to determine the date of production.Since 2063 has yet to pass, and the company did not exist in 1863 nor did it use that symbol prior to the 1950's, the only possible year of production is 1963. I am unsure of whether or not this particular example follows the general trend of date code to the right of the symbol. If we assume that the 7 is indicative of a year, it could mean anything from 1957 to 2007.If you are an avid beach glass collector, or a collector of glass bottles, jars, cups, etc, you may have noticed an odd symbol and/or numbers on your find and didn't know what they meant. Usually, the symbols are a logo for a company, and the numbers a code for where and when the particular glass item was produced.Each glass making company has their own method of labeling their products.
The symbols, therefore, are quite faded.) Production of this particular mark ended somewhere in the mid 1950’s.
