I’m still digging up bottles and other items from my backyard. All date from about 1890’s to about 1913. I was thrilled to dig up one of these on the weekend- unfortunately no embossing of any kind. I am still learning how to spot manufacturing technique, so maybe I could get some opinions from the experts. The seam goes all the around but nothing on the lip. The glass has bubbles and swirls. Would this b type of bottle be blown into a mold and then the top applied? Does any of this help with a date range?
