Can anyone date this bottle? It has no markings at all. I can see a few different air bubbles in the glass and the lip seems too be oddly shaped. The seams also aren’t smooth with the glass.
Hi, thanks for posting. Scout around on the internet for "Citrate of Magnesia" bottles - the shape is distinctive. Yours is later 19th century.
