Half cock hammer for H&R

[Tackleberry41]

I have seen where some got rid of the transfer system in their H&R using a half cock hammer out of another model. They have so many on Numrich, I have no idea what I would need to buy for a SB2 rifle to convert it?

The no transfer bar H&R is a rebounding hammer...looking like a half cock

Okay, whatever the older models had, I wasnt sure what model parts I needed to go looking at on Numrich.

The one I have..410 shotgun, Topper Model 58 on top of chamber
just has Harrington & Richardson on the left side of the frame
Serial number begins with AM25xxxx, this also has the lever next to the hammer, not behind it

Hope this helps
Good Luck
