Hi Tom, thanks for the good pics and post! You have one of the many "Deco" styles of 1920's Coca Cola bottles used around the United States, about 5 years before the vast majority of Coca Cola bottlers were finally able to fully adapt the classic "Hobbleskirt" Coca Cola bottle that was originally patented in 1915. And of course we all know that Coca Cola was formulated in Georgia in 1886, with the first sales as a health drink occurring at Jacobs Pharmacy in Atlanta GA in May of 1886. Your Deco style bottle probably did NOT hold Coca-Cola, as that product was reserved for the standard Hobbleskirt bottles. Many Coca Cola bottlers produced other beverages, like Orange Soda and other flavored sodas, and that was most likely what was in your bottle, along with an attractive paper label to show off the product.
The Seattle Coca Cola Bottling Company traces it's beginnings back to 1906, when a franchise was opened with John M Crain as manager. There are early Coca Cola bottles that date from this time period, hand blown, aqua glass, crown top (bottle cap) closure. They are embossed on the shoulder and heel of the bottle, or on the body of the bottle "Coca-Cola Co. / Seattle, Wash." I don't think the early owners of this company realized what a potential gold mine they had, as the franchise seemed to change hands every year or so in the early days. Finally, in 1915, a prominent Seattle bottle, J G Fox, acquired the Coca Cola franchise and I suspect your bottle is from his years of operation. He was very innovative with unusual bottles and all sorts of oddball siphons, trademarks, labels, etc etc. Mr Fox retained the Coca Cola franchise in Seattle until 1923. In 1924, the Coca Cola Bottling Co of Seattle was purchased by Benjamin Thomas and George T. Hunter, who formed the Pacific Coast Coca Cola Bottling Co. This business remained intact for many decades and was very successful, the true forerunner of the modern Coca Cola operations in the Seattle area. The present plant is actually in Bellevue, and has franchises all around the Puget Sound area.
Hope this is of help, and thanks for the posting!
