Hi again, CCB420, your second-pictured bottle is what bottle collectors commonly call the "D-pat" bottle. It signifies Design Patent #105529. The date that design patent was issued was August 3, 1937. That is the third design patent for Coca-Cola bottles (containing Coca-Cola).
The first one is design patent number 48160 and its issue date was November 16,1915. Bottles had the issue date embossed on them.
The second one is number 63657 and its issue date was December 25, 1923. Bottles had this December 25 issue date embossed on them. Bottle collectors commonly call these bottles "Christmas Coke".
Instead of embossing the patent date, the design patent number 105529 was embossed on the "D-pat" Coca-Cola bottles. (It is not correct to say that their patent date is Dec 25th.)
As far as I presently know, Coca-Cola never sold any Coca-Cola in bottles that look like the design patent drawing issued in 1915. Instead, Coca-Cola did a slight re-design before bottling, and used a shape like the drawing of the Christmas Coke for selling Coca-Cola bottles with the 1915 date embossed on them.
According to Bill Porter's book Coke Bottle Checklist, Coca-Cola first bottled Coca-Cola in this style of botte starting in 1917. The "D-pat" bottles were made during the period 1938 - 1951. Coca-Cola bottles of this style made after 1951 had neither the design patent date nor the design patent number embossed on them. Bill's book has information on how all the date codes on these bottles work.
By the way, my reference for the date code information on the square Coca-Cola soda water bottles made by the Graham Glass company is: Graham Glass Co.
