1970's Dritz Pressing Ham

This Dritz pressing ham is in excellent used condition, having not been used in the last several years.  It was purchased in the 1970's when I was first learning to sew.  It is a plaid wool on one side and a linen backside.  It is likely stuffed with sawdust, but can't be sure. It's measurements are @ 6" W x 10" L x 15" in diameter.
