Its a small kahle hook.look it up and pick a brand.
Yep! All the rage for riggin' back in the 60's. The old man had a box of 'em everywhere. I believe Eagle Claw was the first to produce.
From the Eagle Claw catalog:
"KAHLE HOOKS -This is one of the most versatile hook on the market today. Others may know this hook as a wide gap or a shiner hook but the kahle was built exclusively by Eagle Claw. So versatile, this hook can be used with either live or chunk bait and is great for freshwater or saltwater. Kahle hooks come in a wide range of sizes and colors and can be used for bass, catfish, trout, redfish, drum, flounder, and more."
