I wanted to ask if anybody here could help me with lead knuckles? There is a shop close to my home and close to Chickamauga battlefield that i sometimes buy minnie balls from. They have a pair of knuckles for sale that are labeled "very old" that i really want but i don't know what to look for in them. They are made of lead, and are hand made for sure. How do i tell if they are authentic? What do i need to be looking for? I would be thankful for any advice.
