I found this bottle on a dive trip and have not been able to find any info on it at all. I'm new to this stuff and have probably been looking in the wrong places. If anyone could help me it would be greatly appreciated. It is an old ale bottle with the embossed lettering of Phil Porter & Ale with a small inverted "v" after the word Phil. It has no seams and the end seems to be a blob type. There is some threading around the nipple end though and the bottom is recessed. There are many air bubble embedded within the glass. If any more info is required, just ask. If anyone could help me out it, it would be greatly appreciated. Thank you very much.
