This is an old, wooden, saltwater fishing lure called the Dighton Bass Bomb. It was made from approximately 1949 – 1955, and it’s claim to fame was that a fisherman could change the placement of the hooks from the back to the front which changed the action of the plug. They were made in Dighton, Massachusetts, by the Bass Bomb Bait Company of Dighton, Mass. It’s 6-1/4" long and weighs 3-3/4 oz. This one is marked “Patent Pending” but a patent may never have been given as the company was in business such a short time.
