I have a Eastern Arms (sold by Sears and hardware stores) Manufactured by Iver Johnson as well as others. It is a 16 gauge single barrel shotgun model 1929. The firing pin is removed by cocking the hammer back, there is a set screw at the top of the receiver , when removed the firing pin can be removed from the hammer side;watch for the spring. Installation is the reverse.
There is usually a screw on the top of the receiver in front of the hammer or a pin through the side of the receiver holding the firing pin in.
