The product is a set of two vintage/antique forged metal chain hooks with a clevis grab hook. Made by the brand Mo-Clamp, these hooks are specifically labeled as "C" and "5/16". These hooks are likely used for automotive lifting and support, adding a touch of nostalgia to the process while offering durability and quality. Plus an extra antique hook with purchase. As seen in the pictures. I’m not sure the make of the extra hook. I hope the pictures can answer any other questions. Thank you for taking the time to read my post.
