Im working on restoring an old Marlin 122 single shot from the early 60s. It's a bit of a family heirloom. I have included a picture of a Marlin 122 which provides also a picture of the striker which I'm having issue with securing to the bolt sleeve. I included a two minute video explaining my problem. Thanks for any help.
