Exactly, you can sort through or maybe write Alan's U.K. Bottle Collecting Page. I saw a bunch listed with different numbers. Maybe the numbers were for inventory? I really don't know... yet. I may have to look for that.Unless your bottles can provide us further clues, I think it would be difficult to point to a brewery or soda maker. Cannington, Shaw were prolific makers of bottles and jars back in the day.
