Welcome to Tnet.
It’s not very clear from your picture, but there’s an “Owens-Illinois Glass Company” trademark between the ‘20’ and the ‘7’, similar to this:
It’s a post-1929 mark. Although there are exceptions, the usual coding format for Owens-Illinois was that the plant code was to the left of the logo and the date code to the right. The other letters and numbers will be mould codes and container type.
Plant code ‘20’ was originally for the Brackinridge, PA plant (which was idle in the 1930s, but restarted during WWII to produce covers for land-mines). The code was re-assigned to the Oakland, CA plant in 1936. “Duraglas” (note that it has a single ‘s’) was an Owens-illinois innovation and the word in cursive letters first appeared in 1940 on bottle bases (through to about 1964) so this will be Oakland production. Owens-Illinois were using single digit date codes (the last digit of the year) at the time but recognised during the late 1940s that this would create an ambiguity between 194X and 195X, so they then switched to double-digits. I would think your bottle is therefore probably from 1947.
I would emphasise that there are exceptions to these generalities depending on container type, and a picture of the bottle itself would be helpful.
