Pre-WWII, the infamous Nazi symbol was actually a commonly used symbol by different cultures, especially by Native Americans. Their symbol was called a 'whirling' or 'rolling log'. I think the legs of the Indian symbol may actually 'rotate' a different direction. After the Nazis, it was out of favor due to the terrible connotation associated with it. I would make sure this is actually a 'German' spoon and not a German made spoon with a pre-Nazi symbol on it. If it is a Native American item it may be nice to keep. Pictures of it, as previously mentioned, would be a great help.
