Oops, this bottle has mineral or previous contents staining on all four inside panels. It also has a small bruise on the lip, not a chip. It could be an air bubble. It's been a while since I've looked at it. I dug it about 30 years ago. I also have a nice Arabian bitters that was also dug around the same time.
It is for sale as well if anyone is interested. I have a variety of John Ryans that I'm willing part with too.
