A full set (total weight 20 lbs) of silverware, purchased in Germany about 50 years ago by my parents-in-law. It is not sterling, but I believe it is also not "German silver." It does tarnish. The mark on the back of each piece shows a design plus the numbers and letters "800 OKA"
My parents-in-law owned it. I believe they purchased it in Munich about 1970.
