Won't be of much help to you - but all I can offer.
I bought my NF Buntline new in April 1974 - G8972x
They are great revolvers. I sent the grip frame to David Wayland - he made both custom Mexican Ebony and Brazilian Rosewood grips for it, then to a company in TX for custom stags. Also had a Triple K western rig to carry it. Used it for tree squirrel, ground squirrel, jacks and cottontail mostly, but also shot some predators with the MAG cylinder before I sold it.
FWIW
