Anyone know much about old decoys? I was given this antique mallard decoy several years back as a wedding gift. Would love to know more about it. The only marking I could find was on the lead weight on the bottom. It’s stamped M 7. It appears the head was carved/made separate from the body. On the bottom of the decoy you can see were the hole that was made to attach the head was sealed. The eyes on the head are metal tacks I believe.
