If that is the case, this piece of glass may be our exception to the rule and the 7 to the right of the symbol may not be a year code at all.
(I am also a giant nerd and find this stuff fascinating.) I will never know exactly what year the previous glass was manufactured, but while digging I discovered that I owned pieces, that with a lot of persistence, could be dated to a specific year.
But first a little about the The history is a little confusing, and as is usual of the internet, varies from website to website, with each website having their own sources, and their own account of what happened.

(Lindsey, B.) Though this process is still in use today, the word was embossed on bottles only between 1940 and the mid-1950s (Lindsey, B).Therefore the piece of glass I found was manufactured using this process somewhere in that time frame.an A may mean soda bottle, etc.) In other words, they're not very useful for our purposes.
