I have an SB2 receiver from a complete Buffalo Classic 45-70.
HX prefix. Decent trigger.
This should be a case hardened receiver, but I see none of the blueish coloring left. It was obviously not stored in the most careful way.
pics will speak for themselves. Function is fine.
Might make a good dura coat type project.
