Update on Silver Seal Soda Bottle

I know you have not been able to sleep wondering about the soda bottle we found in the garage slab. Me either. As we were standing out in the rain yesterday chatting, Vern warned T and I that if they run into a privy during the trenching, we'll have all the bottles we ever dreamed of. T, while doubtful it would actually happen, was very excited with the possibility. Anyway, after soaking the bottle in vinegar overnight, I was able to get the concrete off the bottom to observe the bottle maker marks. Here is the bottom of our bottle,

From the web site: http://www.glassbottlemarks.com/ (a neat site), the "N in a square"

was the trade mark of the Obear-Nestor Glass Compay, East St. Louis, Illinois. According to the web site, they were in business from 1894 to 1978. "The 'N in a square' mark was used from approximately 1915 to the glass plant closing in 1978. Often, the mark is accompanied by a date code, usually two numbers located to the immediate right of the “N”, which would stand for the last 2 digits of the year the bottle was made".

On our bottle, there is no number to the immediate right of the mark. The numbers 16 and 46 do appear however. Since the copyright was 1924, I would assume, for now, that the bottle was made in 1946.

This does not pin point the age of the bottle. We still need to find out more about the American Soda Water Company. I need to get this done before we unearth the privy!
