Joshua Longfield North of England Sauce

[John Mount]

Hello! Its been a while since I've picked up any new bottles but this weekend I saw a few I liked including this sauce. Its a common one but a good example or so Im told. Interesting finish, nice lines and bubbles, and some odd ridges on the seam. One thing Ive never seen is the flap of glass sticking out on the neck. Seems a bad idea and I cant imagine what the point of that was. Maybe a mistake? Id

k but here it is!

What can that flap or ridge be for?

That's just from the mold excess glass I assume. Someone on here probably has an exact name for the flaw. Always liked this style bottle.
