Hi "2dogs2people",here are some I'm having trouble finding info on
I don't have much meaningful info to offer, but as I am always interested in date code markings, it is my assumption that two of the soda bottles (one is green, the other one is clear- in your first batch of 10 pictures) have a date code for 1981 on the bottoms (81). One of those has a mold number of "31" and the other one has a mold number "20".
Also, farther down, your base photo of the markings on the clear Coke bottle that is unopened, the "76" is (I presume) a date code for 1976. If you are able to, I'd love to hear any feedback from your father-in-law about those markings and if I am correct! One question I have (if he is able to remember/answer) is this: when existing soda bottle molds in use were re-tooled with a new date code year (such as changing the engraving from a "75" to a "76") did they try to do that right around the very first of the new year, or was there considerable "leeway" in the time period before the bottle molds had to be changed? Hopefully this makes sense! Thanks! David
