This is a fragment from an archaeological site, and unfortunately it is the only part of the bottle we have.
It seems to be mouth-blown and, and I first thought a laid-on ring finish. But looking on the inside (right hand image) it has an internal "thread" or groove which intrigues me. Probably a specialised lipping tool, so I am thinking mid 1800's (1840-1850 ish), but I'm just not sure.
Anyone seen anything like it?
The scale in the photo is 5cm (1.97") long with 1cm graduations.
The site is in Australia, by the way, but given the probable date it will not have been locally produced, so probably US or UK in origin.
