Glass coca cola bottle date

[The Fonz]

Hello all, so I have a question about an old coca cola bottle I recently found, and I am running into a condurum,
The bottle says PAT D-105529 And the date code says 15 L 48


Now according to what I know about date codes this should be a bottle made in 1915, but my research shows that Pat d bottles were not made in 1915. The L I'm assumeing that it is a glass manufacturer mark but I don't know about that

Can anyone help me with a way to know the date, or is this actually a pat D bottle from 1915?

The pictures are of the bottle I'm speaking of, the words in the picture might be hard to read but they are the best ones I'm able to take.
Any help is appreciated!

The 48 number is the better number I believe

I will add if it was a 1915 it would have Nov.16.1915 instead of the patent D numbers

 

[J.R. Collector]

Hopefully you can see the date here. Picture isnt the best.

1917-1930 for that one. Is there any other codes on the heel or bottom. The l could be laurens glass works.

So is the 48 on here the mold code? Robby? I thought pat D where atleast 1930 and on?

The only other markings are on the bottom, in all capital it says Dover del.
Could you tell me how to acurately read date codes? Such as is the front 2 numbers always the year? And what would that make the last 2 numbers?

Would the D be from Dominion Glass or Domglass. They began putting D on bottles in 1922

D means design If it is early it is probably made by graham glass. They had 4 locations. If so the L would mean Loogootee-Indiana.

All D-Patent Cokes were made between 1938-51. your 48 # is the Date. 1948. LEON.
