What does 14k GWR on the inside of a late 1960's mens wedding ring mean?

okay, i have had quite a bit of research for this for you (currently at 4.32am in the morning and needing much deprived sleep) but anyway, i found an answer from www.about.com which hopefully answers your question...
"The karat marking on your gold jewelry should be accompanied by a hallmark or trademark that identifies its maker. The item's country of origin might also be included."
Perhaps if it is not the artist of the ring who produced the piece, then perhaps it is the country like England for example. unfortunately, my grandfather who is a watchmaker would know this grand question but is sleeping at this hour i imagine
hope u have some luck
cheers, d
