Have the hooks been worked on?? Resoldered?? I ran across a guy in the 90's who casted buckles from "supposed bannerman" specimens. I had bought some Breckenridge and Texas plates that ended up being duds. Use them mainly for visual or reenactment purposes.
I'll let you decide. Below is an original Bannerman's that I have in my collection. I got this plate from LP on a trade and it is a known Bannerman's in the original shipping box.
