Demijohn glass green breath

Very old lady jeanne in blown glass. The very old ones are easily recognizable by their neck that is not cut clean, it is mostly non-lime and like ebreche. This one is blown and shaped wrongly. We can see in the photo that his neck is leaning. The glass is green in color and quite thin, so more fragile. It has many bubbles and nets. The bottom has some scratches because it has served a lot. The neck is embellished with a collar to less weaken it. They become rare, the very old.
