The one on the left the stops at the bottom of the lipI'm afraid you did not get it right. They're both machine made and both date to around the 1920s, give or take a decade. An applied top bottle won't have the seam through to the top of lip or the suction scar on the base.
Thank you- while I’ve been hunting and digging and collecting and learning about this for more decades than I want to admit, you just broke it down to a paragraph and made it simple to understand. You should write a book because i just haven’t found this written in such a fashion in all the books I’ve poured over, out there! I am here to learn! Beyond that, pretty much self taught....Applied top bottles are typically before 1885. You can usually see where the applied top meets the body of the bottle. The tops were otherwise formed when the glass was shaped with a lipping tool while still just soft enough. The neck was usually reheated to do this. Tooling the top was faster than applying a new piece of glass and so was the preferred method after the technique was perfected. Mold seams are a poor identifier for age as they are determined by the condition of the mold and the gaffer's skill level
