Bought 3 H&Rs at an auction this last week. This is the oldest.
This is a 32 rimfire pat date on left side of barrel is May 23, 1876
There is a small spring that hooks into the half circle cut at the arrow that presses on the ratchet arm.
The 3 digit serial number is at the bottom of the grip frame.
The grips are the star over shield type.
