1800’s black powder cartridge loader

This is a Snider 2 band Sargents model. Queens Own Army. 1800’s black powder cartridge loader.  It’s old and in ok condition for its age. I don’t know the history of this gun, my uncle died before I could get its significance in his collection. The breach and ramrod are missing. Otherwise it’s all there and original. It’s a .577 cal. I have another post with some ammo. I am open to offers. I live in the Midland area.
