This is a New Firing pin Winchester 22 pump rifle. This part fits model 1890 or 1906 (the firing pin 62 or 62A model is part numBer 742) The firing pin spring is part number 741spring. NOTE: I have found that some early first model bolts have a smaller opening at the Forearm so the fat part of the back of the firing pin needs to be filed down a little bit to get it to fit in the bolt. In case you are looking for an ORIGINAL please look up part WP207
