Another one that's been puzzling me is this...
The marking that I can make out are C Sharps Pat Sept 12th 1848 and Caliber 30 30.
It has an octagonal barrel, double trigger and looks like a model 1949 or 1950 but doesn't match the pictures I can find exactly.
It has a silver tip where the wood stock ends instead of a band and the caliber with the double trigger doesn't match either. I read that sometimes officers weapons had the silver tip? No serial number or any other markings were visable.
