I was painting masking fluid on my cod piece tonight and I noticed something as I was studying reference photos. This is from the tdh archive so please correct me if I should not post the pic. I have cropped it to show only necessary parts. This is of the right side of the cod piece while wearing it. Is this a bolt head? I thought it might be a way that they held the cod and backstrap together? Someone is bound to know the real story so please help me out!
