Re: Dog tags from WWll?
Undoubtedly not a Korean War tag, Sue. The Korean War armistice was signed in July, 1953.
Your other post appears to clear up the mystery about the fourth line. With that info (his religion), it suggests very strongly that the tags came from the Vietnam era. Go to this web page and click "Vietnam Era '54-'64". I'm guessing the example there will be like the tags you asked about.
As I said, I am only a hobbyist, but the "evidence" looks pretty clear.
Of course, as to where the tags came from , what connection they had to your family, etc, I have no clue.
