So after months of looking for it, I find the thing 3 days after asking for a replacement. Naturally. Appreciate the offers to help though!
It was an 8" bolt, by the way.
Picture of it below, though picture is bit bleached out (cell phone camera). Top is an 1899A SR, serial number 10.75x, bottom is the 1899C trapper serial number 12.14x. Fun, cheap guns.
