Firing pin appears to be a Remington 742/760.
I don't think that one part is a hammer... more like an ejector/bolt stop... weird looking part.
Looks like a shell stop/lifter for a 22 rifle.That is possible, I just assumed it was some kind of trigger-group mounted hammer, like you find in pumps and semi-autos. It is quite thick and one of the leading edges seems to show signs of strike wear (see arrow in pic) and has what could possibly be a sear notch. But you are right, it is a weary looking part.
