Thank you for the video. Well done. Don't beat yourself up about the mistake. Even I have made one once. Of course that was when I thought I had made a mistake.
My specimen has little rust spots (well oiled now). It was left unattended for about 20 years. It's a great shooter. I will dispose of it because I am old, can't see the sights, and no one in my family is an enthusiast. That pistol has the cleanest breaking trigger I have ever felt.
Thank you again for your help.
