Hopefully this picture link worked! Here's what I've been told of this bottle from the seller:
Antique Hindle and Co (Blackpool) Codd Stopper pop bottle. Cornflower blue, 10 0z. This method of bottling early carbonated beverages was invented by Hiram Codd of Britain. There is a vulcanized rubber ring inside the mouth of the bottle that looks just like a white sealer ring would look like. The ring is aged and hardened. There is a marble suspended in the top portion of the bottle. The marble was forced upward by the carbonation thus sealing the drink. After opening you had to pour in the direction that the marble would catch on the indents and not go up and plug the drink while you drank it. It is said that children would often smash the bottles to get the marble. Apparently this one was discovered in Halifax Harbour (east coast Canada) by a hobby diver. There are two seams evident on opposite sides that disappear in the top inch of the bottle. There are a few tiny gas bubbles evident within the glass. On the bottom there is a funny M with outwardly curving sides with an x inside the M, below the point. It also says 10 oz and 11A2. The glass looks remarably shiny and newish. I was told it was made around the turn of the century. I would like to confirm the age of this bottle and find out any more information as is possible.
