Thanks to all that have taken the time to reply. Had an illness in the family so I haven't been able to get back here, didn't intentionally ignore your help. My serial number is indeed below your mentioned 4,580,000, its 400023xx so now I know why my info doesn't seem correct. Can someone direct me to a site that will have parts? I would like a new receiver screw set and possibly a firing pin and some other odd parts. Again, I do appreciate your taking the time to help!
