Hi everyone, I'm new here and hoping you can help me learn more about my rifle.
My grandfather had this rifle stored for the past 40 years in San Francisco. It was covered in rust, so I took it apart and cleaned it up. Here's what I know:
Barrel is about 33.5", 35" with the chamber
3 line patent marking with the latest date being 1873 (maybe 1874, really pitted!)
Left side of the barrel has a faint "B"
Left side of both the top and bottom stock tangs on the receiver have serial markings "E61190"
Right side, lower tang has a modified "F" stamped
"X" marking to the right of the chamber
"U" stamped on barrel bands
"315" engraved on right side of the stock
"22" engraved on the stock, under the receiver tang mount
Caliber seems to around .45
Rear sight has "1-2-3-4" markings on left side
Extractor is pinned, not screwed
When you close the block, the hammer stays cocked and ready to fire

Thanks for the help! I'm a M1911 guy and don't know much about old rifles!
