Yugo M57 firing pin replacement/cleaning instructions

I spent 4 hours trying to get that %$@#@#$% firing pin back together. I left ALL the pieces lying on the table to go to bed, did a search of the forums to find out what I was doing wrong, found a link to this video, went to bed dreaming of a GOOD DAY to come. The next morning I re-watched the last section of the video as a refresher. Went back to the table, 5 minutes, DONE! My fingers are Older and Fatter than the person in the video so I did need to hold on to the retainer with a pair of needle nose pliers.
Best video I have ever seen; on assembling the firing pin, and assorted springs, retainers, for the M57 Tokarev pistol. After four hours of pure torture, I watched this video and completed the task in 5 minutes. Watch and be amazed at how SIMPLE it really is.
