Why does the bolt have two legs on the hammer end, when only one leg rides on the cam? Is it so the other leg rides against the frame and puts pressure on the other leg to keep it on the hammer cam? The bolt does look like it was stoned some where it protrudes up through the frame to contact the cylinder (looks like it was rubbing on the frame and was stoned on the "outside" to give it clearance), and it looks like it has rubbed the bluing off where the leg rides against the hammer, but I don't see and sign that the leg was trimmed on stoned on the end to make it shorter. I hope the relationship (length) of the frame between hammer and bolt isn't out of spec.
Again, thanks for the help, and any one else with ideas feel free to chime in.
