Hello all. I have a Euroarms made 1803 Harpers Ferry rifle. Perhaps the jaw screw was not properly hardened at time of manufacture. On pulling the hammer back the crew bent to such a point I cannot remove it. I am afraid of messing up the threading on the hammer. Question is how can I remove it safely and question 2 is where can I get a replacement screw? I cant seem to find one. Any help is appreciated. Thank you so much.
