If only it coild talk...

[JH1961]

This lock is on a really rough long gun once used by Apaches. The butt stock has been shortened, but the lock is what is interesting. If nor mistaken, it's an 1861 Enfield. The firearm has no sights at all.

Could you post more photos, particularly of the entire gun as well as any markings?
Also, would be interested as to Apache provenance.
