Nice looking 1892. Appears the original rear sight has been swapped. Value probably in the $1000+ area.

Appears to be missing finger lever pin retaining screw. Hopefully it isn’t also missing finger lever pin. That little pin holds a lot of other stuff in place too. Like the ejector, firing pin, firing pin & egector spring, etc.

Thanks... Don’t know the history I’m just going off of pictures that was sent to me…

Yeah rear site. The correct carbine ladder site is a spendy piece when you can find one. Not the most common caliber I'm thinking in a saddle ring 92.
