A. T. Coy. No base mark. Rough stopper is embossed: Barrett & Elers Patent London with screw thread stopper pictorial. (New South Wales). Aerated Water. Internal Thread. Shouldered cylinder. Applied double collar top. Aqua. 5 oz. 172 mm without stopper. 1890s
Very Good. (7.9). Patchy light stain. Some scratches and minor marks. Stopper would be a beauty but is quite damaged. Mystery bottle. These turn up around Goulburn in NSW (as in fact this one did) but are not attributed to any company. A quick search of Trove reveals there was a Timber company on the mid-north coast of New South Wales known as the A. T. Coy. But realistically if it is a NSW bottle it could be very difficult to get a definite answer. As it stands this is an interesting early internal thread. Estimate: $100-200
