I bought this at an estate sale and I know nothing about it. I don't know if it is a reproduction or what. It is a smaller size. I wonder if it might be a Navy WAVE ring---?? Size is a good 9 1/2. (I do not think this ring can be resized.) It is not sterling. I think it is a heavy metal ring but your guess is as good as mine. It is interesting. It has the anchor on it. It has a "J" on one side and a "W" on the other side of the ring. ?? Initials are not highly visible.
