From what I can see in your pictures the part hanging down appears to be the rear 2/3 of the firing pin - the front is broken off & missing. I assume you have not tried to fire this gun - if you have and it fired then I am wrong about what I see in the picture and the rest of this post would then be of no use.
I will continue assuming the firing pins is broken as it appears to be in your pictures.
There is a small slot in the firing pin that is held up by a small pin through the receiver - yours appears broken off through this slot so it does not engage the pin. New firing pins are listed on GunParts (Numrich) but a person ordering one got a version for a late style bolt and it will not work in your bolt and I do not think one could be made to work - you would have to talk to them to try and see if they have the correct pin if you go that route.
A complete late style bolt should fit so that would be another option. There were several changes to the firing pins & bolts in these over the years.
