I have a bottle I found years ago while diving. It is a clear glass bottle with Waterfill Frazier on the front with a "federal law forbids the sale or re-use of this bottle" and the letter and numbers D 685. On the back are the words ONE PINT and on the bottom 60-42. The most interesting thing about this bottle is the coloring, although it is a clear bottle, the coloring in the light is rainbow colors similiar to an oily sheen reflected off the sun on water or light coming through a prism or mist. Any information on this bottle would be helpful. Thanks.
