These cones are unlabeled, so we don't know the exact details, but they are vintage Scottish, woolen-spun weaving yarn from the mid-20th century. The yarn is a somewhat coarse and hairy wool , in a reddish-brown color. It appears to be a 12/2 or possibly 10/2 yarn. The cones range in weight from 8.0 to 9.1 ounces and are estimated to be 1350 yards (assuming that it is 12/2).

The cones have different colored tips - blue, dark green and light green - that typically mean primary or secondary (mill end) production runs.
