An early solid cast iron sink box duck decoy measuring 13 1/4" tail to nose, 6" to top of head and about 7 at its widest. I'm guessing it weighs roughly 30 lbs given the weight and size of other sink box decoys I've looked at. The initials JCB in the mold are on one side and the number 1824 molded on the other side. I have not seen any online with cast initials. Nothing is on the bottom.
From my father's 60 year decoy and antique collections. We have no other decoys available at this time.
