thanks. this has been very frustrating. seems simple like 1921, but then i saw a bottle online somewhere which had 48 punched into the paper but was listed as being made a decade later (i chose those dates arbitrarily). i dont know these type bottles at all. starting to enjoy them though.
Hey sorry, I had seen this post but I'm so busy I forgot to comment. Some of our bottlers that used paper labels also had hole punched numbers, originally I thought it corresponded to a date.
On this example the numbers are 9. 1.36 so I figured September 1, 1936.... and that year is perfectly in line with the bottles era. But a friend of mine has an examples from the same bottler and the numbers don't make sense for a date. So it must be for a batch#.. ???...but at this point I'm not really sure.
