Assuming it is BIM (which it looks like it is) I'd say it dates most likely to 1880s-1890s. It just doesn't have the characteristics of a heinz that is older or newer than that. The older ones are usually embossed Heinz and Noble and the newer varieties are noticeably machine made or late BIM and usually say H.J. Heinz Co. I can also see yours has some kind of imperfection on the base.
Usually heinz bottles have code numbers that can be matched to what was inside the bottle. Does yours have this? Also I've never seen a heinz of this particular base embossing before.
