Just came across your post looking for information about my J Russak bottle I found on a ship wreck of the North Norfolk coast in the uk about 20 years ago. I have wondered what it contained how old it was and where it came from since I found it. When found, it was corked and still full but as I ascended from the dive there was a loud pop which caused me some alarm until I realized the cork had popped. I would like to know more about it as I have always wondered why it has cities embossed on it.
