It may be an applied lip, feel inside where the top meets the neck, and if you feel a lip or size differencewhere they join, it is applied, I cant really tell by the pics. Looks like a mineral water, like a Hunyadi Janos only different shape. it looks like a quart size??. spun mold maybe, 1880 - 1900. somebody else will join in I am sure and maybe have better info........Andy
British imports here are still common today. The British made blob bottles into at least the 1930s. I've seen 1910's-era examples of applied-top bottles by their glasshouses. A better way to tell the age is to analyze the site and to try and find records.
So the bottle looks like a good one. At this point we need more information about it. Bottles of this tyYoupe can be made in three part molds - in that case there would be a horizontal seam on the shoulder and two vertical seams up the neck to the obviously applied and tooled finish.You didn't tell us anything about the bottom of the bottle - but if it was hand blown it should have evidence of an empontilling handle having been there.So we have to know more about the details, RED Matthews
To me it looks like a generic (unembossed) German-blown beer similar to those blown for the Western market in the 1890s. Granted the lip finish is flatter. But that was my first thought upon viewing the pictures.
