HELLO ALL, I have this bottle that came to me with an unusual story that I will post later as I do not want to taint my search for valid info. First, I am a very novice bottle-head, so please bear with me and forgive my clumsyness. If you look at the photos you will see this is pretty tall at nearly 13 inches. The seam stops and the top 3/4 ths inch is smooth. But is is certainly not blob-top. There is no marking that I can find except for a mark on the well worn bottom. The thicknes of the bottom is uneven and there atre several air bubbles. I have more pix I you want.
