Sure, most of the comparisons I used to compare to my 1941 1/2 pint in the above came from the following site https://sha.org/bottle/index.htm
The others was by googling the following - bottle Rectifiers list, User Permit lists & Industry liquor bottle plant numbers
In my research, I did not want to solely rely on the Rectifier numbers to Identify the age of the bottle, I wanted to know, what it was of the 41's shape, Mold features, including such as the feature of the kork-N-Seal that was supporting the data,
