JayCee, I'm not sure what your question is, but tung oil is produced from the nuts of the tung tree (China, South America). By itself, it is as useless a wood finish as raw linseed. As a finish component it has great value and apparently some advantages over linseed, such as better moisture resistance and less of the warm amber color of linseed. Personally, I don't see this as any advantage where gunstocks are concerned, but on very light colored woods it is.
