Thank you very much for your reply Charles. Im a taxidermist by trade, and very familiar with locks. I agree with you on the contact marks. A muddy set gets worn real quick too. The exception is when the locks are caused by the animals muzzles or skulls along with the antlers. If theres any question about the authenticity, I ask for pictures from the site. Theres almost always pics from where they found them. Wish me luck!
