This cone is unlabeled, so we don't know the exact details, but it is a vintage Scottish, woolen-spun weaving yarn from the mid-20th century. It is definitely on the hairy side, in a grayish blue with gold highlights. Its original color may have faded a bit with age. It appears to be a 1/10 count yarn. The cone weighs 8.6 ounces and is estimated to be 1100 yards. It is likely a full or nearly full tube. 

This is a classic weft wool produced by Scottish mills in the mid-20th century.
